**Talk Math**

What should you do if the remainder is greater than or equal to the divisor?

Answer:

If the remainder is greater than or equal to the divisor,

the divisor can continue to be divided into it.

Explanation:

If a remainder is more than divisor, it can go one more time and division is not complete.

Even if remainder is equal to divisor, it can still go one more time.

Hence remainder has to be less than the divisor.
