Step 1-group the digits in pairs,starting with the digits in units place.each pair and a remaining digit (if any) is called a period. step-2 - think of the largest digit whose square is equal or just less than the first pair(from left) step3-subtract the product of the divisor and the quotient from the first period and bring down the period to the right of remainder. step4-now the new divisor is taken by takin two times of current quotient.repeat the steps
