A number by which another number is to be divided

Dividend

Step-by-step explanation:

If you take a simple division problem like A = B / C

A is the quotient (result)

B is the dividend

C is the divisor

So, a number by which another number is to be divided is called a dividend, like A in the example above.

If C doesn't divide B in an exact manner (like in the case of 7 / 2), there's a remainder for the operation.
