If you want to divide whole numbers first, divide the first digit of the dividend by the divisor
if the divisor is larger than the firs digit of the dividend, divide the first two digits of the dividend by the divisor, and so on.
second, is write the quotient above the dividend.
then, multiply the quotient by the divisor and write the product under the dividend
then substract that product from the dividend
bring down the next digit of the dividend
