# Lesson 11: Dividing Numbers that Result in Decimals

Let’s find quotients that are not whole numbers.

## 11.1: Number Talk: Evaluating Quotients

Find the quotients mentally.

$400\div8$

$80\div8$

$16\div8$

$496\div8$

## 11.2: Keep Dividing

Here is how Mai used base-ten diagrams to calculate $62 \div 5$.

She started by representing 62.

She then made 5 groups, each with 1 ten. There was 1 ten left. She unbundled it into 10 ones and distributed the ones across the 5 groups.

Here is her diagram for $62 \div 5$.

1. Discuss these questions with a partner and write down your answers:

1. Mai should have a total of 12 ones, but her diagram shows only 10. Why?
2. She did not originally have tenths, but in her diagram each group has 4 tenths. Why?
3. What value has Mai found for $62 \div 5$? Explain your reasoning.
2. Find the quotient of $511 \div 5$ by drawing base-ten diagrams or by using the partial quotients method. Show your reasoning. If you get stuck, work with your partner to find a solution.
