Concept: By placing bars on the first two digits of the number and beginning at the unit position, we can use the long division method to determine the square root of 625. The divisor whose square is less than or equal to the dividend will be the large number. The quotient, which will be the same as the divisor, will be written. The square will be subtracted from the dividend. We'll be given a number. The following pair will then be brought down. This will start off as the dividend.
