Division (math)

Division is the mathematical function in which a value, the dividend, is seen in a specific conjunction with another value, the divisor. The relationship between them, which is the value by which the divisor must be multiplied to yield the dividend, is referred to as the quotient. Division yields a non-linear change in value.

Division by zero is undefined, and this has unfortunately been one of the two most frequent sources of serious mechanical or construction errors (the other being wrong units).
