tips for finding square root by division method:
- Group the digits in pairs, starting with the digit in the units place
- Think of the largest number whose square is equal to or just less than the first period. Take this number as the divisor and also as the quotient.
- 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.
- 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.
- Repeat steps till all the periods have been taken up
