Division can be used in partition or breaking down into small quantities. Division also helps to get correct and equal proportions, depending on what is in question. To do division, you need to divide the dividend by the division to get the quotient. The dividend is mostly the numerator and the divisor is the denominator, and the quotient id the number of times a divisor goes into a dividend.
