Long Division Method: Finding Square Root

How to do Long Division in 6 Steps Class 8 & Class 10?

Here we will provide you with the steps to use the long division method easily. Below we will find the root of 529:

-1st Step: Put a bar over the pair of digits starting from the one’s place. For odd digit numbers, the left-most single-digit too will have a bar.

-2nd Step: check for the greatest no. whose square is less than or equal to the number under the extreme left bar ( 2² < 5 < 3²). This will be the divisor. The quotient under the extreme left bar is the dividend (here 5). Divide to get the remainder.

-3rd Step: Take the number under the next bar to the right of the remainder to get the new dividend.

-4th Step: Double the quotient and enter it with a blank on its right.

-5th Step: Imagine the largest possible digit to fill the blank that will also become the new digit in the quotient, so that the product is less than or equal to the dividend.

-6th Step: If the remainder is 0 the process is over else continue the above steps.
