1 ) Group the digits in pairs , starting with the digit in the units palce.Each pair and the remaining digit is called a period .

2 ) Find the largest number whose square is equal to or just less than the first period. Take this number as the divisor and as the quotient.

3 ) Subtract the product of the divisor and the quotient from the first period and bring down the next period to the right of the remainder. This becomes the new remainder.

4 )Now , the new divisor is obtained by taking two times the quotient and annexing with it a suitable digit which is also taken as the next digit of the quotient chosen in such a way that the product of the new divisor and this digit is equal to or just less than the new dividend.

5 ) Repeat steps 2, 3 and 4 till the periods have been taken up.
