In Mathematics, decimals are specific types of numbers, with a whole number and the fractional part separated by a decimal point. The dot that exists between the whole number and fractions part is called the decimal point.

We can also perform various arithmetic operations on these numbers, such as addition, subtraction, multiplication and division.

## Dividing with Decimals

Dividing Decimals is similar to dividing whole numbers, except for the way we handle the decimal point. There are two different cases in dividing decimals, such as:

- Dividing Decimals by whole numbers
- Division of a Decimal Number by another Decimal Number

However, when we divide decimal numbers, we may get a decimal or whole number. Let’s understand the division of these decimals in detail here.

## Dividing Decimals by whole numbers

There will be certain **rules for dividing decimals** in maths. These can be observed from the illustrative examples below.

The step wise procedure for dividing a decimal number by a whole number is given below for 1926 ÷ 4:

**Step 1: **Write the given division expression in the standard form.

**Step 2: **Now, we have to divide the decimal number’s whole number part by the divisor.

**Step 3:** Place the decimal point in the quotient above the dividend’s decimal point and then bring down the tenths digit.

**Step 4: **If the tenths digit of the obtained dividend cannot be divided by the divisor, write 0 in the quotient and in front of the tenths digit. Otherwise, proceed with the division process.

**Step 5: **Repeat the above step and keep adding the zeroes in the dividend until 0 is obtained in the remainder.

Therefore, 19.26 ÷ 4 = 4.815

That means, the quotient is 4.815 and the remainder is 0.

In this example, we considered only those divisions in which the number would be completely divisible by another number to give the remainder zero. However, there are some situations where the given decimal number may not be completely divisible by another number, i.e., we may not get a remainder zero. This can be understood from the example given below.

## Division of a Decimal Number by another Decimal Number

When we divide decimals, we have to convert the divisor to a whole number by moving the decimal point to the right. Then, we carry the dividend’s decimal point up to the same number of places to the right and divide the resultant numbers in the usual way as we perform in regular long division. This can be better understood with the help of the following example.

23.184 ÷ 0.3

The given Divisor = 0.3 and Dividend = 23.184

Change the divisor 0.3 to a whole number by moving the decimal point 1 place to the right. Then move the decimal point in the dividend the same, 1 place to the right.

23.184 ÷ 0.3 = 231.84 ÷ 3

Now, divide the decimal number 231.84 by the whole number., i.e. 3.

### Dividing Decimals examples

The below solved examples help you in better understanding of the division of decimal numbers.

**Example 1: Find the quotient for 1.764 ÷ 0.012.**

**Solution:**

The given Divisor = 0.012 and Dividend = 1.764

Now, change the divisor 0.012 to a whole number by moving the decimal point 3 places to the right. Then move the decimal point in the dividend the same, 3 places to the right.

1.764 ÷ 0.012 = 1764.0 ÷ 12

Thus, the quotient is 147.

**Example 2: Calculate: 8.91 ÷ 2.2**

**Solution:**

The given Divisor = 2.2 and Dividend = 8.91

Now, change the divisor 2.2 to a whole number by moving the decimal point 1 place to the right. Then move the decimal point in the dividend the same, 1 place to the right.

8.91 ÷ 2.2 = 8910 ÷ 22

### Dividing Decimals Problems

Solve the below practice problems on decimal’s division.

1. Divide 0.4545 by 3.6.

2. Find the remainder when 651.2 is divided by 0.04.

3. Evaluate: 7.75 ÷ 0.0025

4. Find the quotient of 82.44 ÷ 18.

### Dividing decimals by 10, 100 and 1000

Let us find the division of a decimal number by 10, 100 and 1000.

Consider 97.5 ÷ 10 = 9.75. Thus, the digits in 97.5 and 9.75 are the same, i.e., 9, 7, and 5, but the decimal point has shifted (towards left) in the quotient. Therefore, in a decimal division by 10, the decimal point will shift to the left by one place since 10 has only one zero over 1.

From the above example, we can say that in the division of decimals by 10, 100 or 1000, the number and quotient digits will be the same. However, the decimal point in the quotient shifts to the left by as many places as zeros over 1.

## Frequently Asked Questions – FAQs

### How do you divide decimals step by step?

Step 1: Write the given division expression in the standard form.

Step 2: Now, we have to divide the decimal number’s whole number part by the divisor.

Step 3: Place the decimal point in the quotient above the dividend’s decimal point and then bring down the tenths’ digit.

Step 4: If the tenth digit of the obtained dividend cannot be divided by the divisor, write 0 in the quotient and in front of the tenths’ digit. Otherwise, proceed with the division process.

Step 5: Repeat the above step and keep adding the zeroes in the dividend until 0 is obtained in the remainder.
