Why might a division problem have more steps than the number of digits in the dividend?

• Because the divisor is large

• Because the dividend is small

• Because the divisor is small

• Because the dividend is large

In the example of 315,270 divided by 5, why is it important to bring down a zero?

Why is it helpful to memorize the multiplication table for division?

• It helps in quickly finding division answers.

• It makes addition easier.

• It is not helpful at all.

• It helps in subtraction.

What should you do after solving a long division problem?
