Division is one of the four basic arithmetic operations. It is the opposite of multiplication and is indicated by using the sign $÷.$ This operation represents the process of calculating how many times one quantity, called the divisor, is contained within another quantity, called the dividend. The result is called the quotient of the division. As already stated, division can be represented with the sign $÷.$ However, there are other ways to represent it. Another common notation is using a a diagonal bar or using fraction notation. If the result of a division is not an integer, the quotient is the number of times the divisor is contained in the dividend, and the part of the dividend that remains is called the remainder. Division is not commutative. This means that changing the order in which the operation is performed leads to different results.
