Binary Division

What is Binary Division? Division is probably one of the most difficult operations of the basic arithmetic operations. The binary division operation is similar to the base 10 decimal system, except the base 2 system. There are different ways to solve the division problems on binary. Long division is one of them and most easy and efficient way. This section has been designed to answer questions about binary division, including:

Binary Division Rules

Binary division is much easier than the decimal division when you remember the following division rules:

÷ 1 0
1 1 Meaningless
0 0 Meaningless

Similar to the decimal number system, the binary division is similar which follows the four-step process:

  • Divide
  • Multiply
  • Subtract
  • Bring down

Important Note: Binary division follows the long division method to find the resultant in an easy way.

Comparison with Decimal Value

(01111100)2 = (1111100)2 = 12410

(0010)2 = (10)2 = 210

You will get the resultant value as 62 when you divide 124 by 2.

So the binary equivalent of 62 is (111110)2

(111110)2 = 6210

Both the binary and the decimal system produce the same result.

Examples:

Solve 01111100 ÷ 0010

Solution:

Given

01111100 ÷ 0010

Here the dividend is 01111100 and the divisor is 0010

Remove the zero’s in the Most Significant Bit in both the dividend and divisor, that doesn’t change the value of the number.

So the dividend becomes 1111100 and the divisor becomes 10.

Now, use the long division method.

Binary Division

Step 1: First, look at the first two numbers in the dividend and compare with the divisor. Here 11 is less than 10, then add the number 1 in the quotient place. Then subtract the value, you get 1 as remainder.

Step 2: Then bring down the next number from the dividend portion and do the step 1 process again

Step 3: Repeat the process until the remainder becomes zero by comparing the dividend and the divisor value.

Step 4: Now, in this case, after you get the remainder value as 0, you have zero left in the dividend portion, so bring that zero to the quotient portion.

Therefore, the resultant value is quotient value which is equal to 111110

So, 01111100 ÷ 0010 = 111110

Example 2: Solve using long division method

101101 ÷ 101

Solution:

Binary Division example

In this case, when you compare the dividend with the divisor, the values are equal.

I.e., 101 = 101

So, when you bring down the fourth bit of the dividend, it does not match with the divisor. In order to bring down the 5th and 6th bit of the dividend, add two zeros in the quotient value. So that when you compare 101 with the divisor 101, the values become equal.
