Operation under which every pair of numbers

*D*and*d*, called the dividend (*D*) and the divisor (*d*), is made to correspond to a new number called the quotient (*Q*) of these two numbers, so that*D*=*d*×*Q*.The inverse operation of division is multiplication.

### Notation

The symbol for division is “÷” which is read as “divided by”.

### Example

Consider the division of these whole numbers: 35 ÷ 7 = 5

The number 35 is the dividend, the number 7 is the divisor and the number 5 is the quotient.

### Historical Note

The symbol ÷, called the *obelus* or *obel* (from the Greek term οβελοσ), was introduced by the Swiss mathematician Johann Henrich Rhan in his treatise on algebra in 1659. He also introduced the symbol * as the symbol of multiplication.
