Answer:

if you wanna do long division you have to simply just follow a procedure that is nice and easy so long division method is mainly need to find the square of a number with out using the prime factorization method the procedure is consisting of these of two steps

  • Obtain the number whose square root is to be computed

  • place bars every pair of digits starting with the unit digits .Also place a bar on one digit if any not forming a on the extreme left. each pair and the remaining one digit (if any) on the extreme left is called a period

  • think of the largest number whose square is less than or equal to the first period . if this number as the divisor and the quotient

  • put the question above the period and write the product of divisor and question just below the first period.

  • subtract the product of divisor and quotient from the first period and bring down the next point to the right of the remainder this becomes the next dividend.

  • double the question as it appears and enter It to the blank on the right for the next digits, as the next possible divisor.

  • think of a digit to fill the blank in step 6 in such a way that the product of new divisor and its digit is equal to or just less than the new dividend obtained in the step 5 .

  • subtract the product of the digits chosen in steps 7 and the new division from the dividend obtained in step 5 and bring down the next period to the right of the remainder of this becomes new dividend .

  • repeat the steps 5 6 and 7 till all the periods have been taken up .

  • obtain the quotient as a square root of the given number .

Hope it helps
