The divisor is the number that divides the dividend in a division operation.
In the context of division, we have three key components:
- Dividend: The number being divided. According to the reference, "the number which is getting divided here is called the dividend."
- Divisor: The number by which the dividend is divided. The reference specifies that "the number which divides a given number is the divisor."
- Quotient: The result of the division.
Therefore, to directly answer the question, the divisor is the number that performs the division on the dividend.
