We use long division method to find the square root of 529. For that, we will group 2 numbers from right to left and then proceed with the division. We add 0 before 5 to make a group of two.

$\begin{array}{cc}& 23\\ 2& \overline{05}\overline{29}\\ & -4\\ 43& 129\\ & -129\\ & 0\end{array}$

Hence, the square root of 529 is 23.
