Since division is the inverse of multiplication then
Definition
If and , then , where is the dividend, is the divisor, and is the quotient.
Process

Dividing Special Numbers
Fractions
If you divide by a fraction, multiply the dividend by the divisor's reciprocal (Note: You will see a definition of a reciprocal if you go to the article Ordinary Multiplication).
For instance:
Decimals
When dividing by decimals, multiply both sides by a power of 10 so the divisor is an integer.
For instance:
One and Itself
Any number divided by one equals itself. Similarly, any number divided by itself equals one.
For instance: and
Zero
Division by is undefined. Equations where any values are divided by will become undefined also.
