I Can determine how many digits a whole-number quotient will have and use long division to divide.

**Spark Your Learning**

Aseem and Chadda have 316 photos to put in 2 scrapbooks. They agree to put the same number of photos in each book. But they disagree about how many photos that is.

Aseem: We can put more than 100 photos in each book.

Chadda: We don’t have enough photos to put 100 in each book.

Who is right? Show and explain your thinking.

Answer:

Therefore, the number of photos in each book are 158.

Aseem is right because more than 100 photos can be put in each book.

**Turn and Talk** How many digits are in the whole-number quotient for 316 ÷ 2? Use place value to explain.

Answer:

There are 3 digits in the whole number quotient.

1. Fran has 423 scrapbook stickers. She wants to put an equal number of stickers in 3 different scrapbooks. How many stickers can she put in each scrapbook?

Find 423 ÷ 3.

Answer:

Given,

Fran has 423 scrapbook stickers.

She wants to put an equal number of stickers in 3 different scrapbooks.

So,

Therefore, she can put 141 stickers in each scrapbook.
