Set the auxilary field on the left equal to the divisor. Step2 Put the dividend into the primary operations section.
Step3 Divide each section as you would on paper, keeping track of the quotient in the right auxilary field. Subtract the number of the quotient multiplied by the divisor from the dividend between each section so that you have a method of checking for accuracy.
Step4 Stop when the dividend is no longer equal to, or greater than, the divisor.
