Main Idea/Vocabulary I will divide up to a three-digit number by a one-digit number. remainder
Example 1 A baker will put 84 carrot muffins in boxes that hold 6 muffins each. How many boxes will the baker fill? To solve, divide 84 muffins into 6 groups. Find 84 ÷ 6. Estimate 84 ÷ 6 80 ÷ 5 = 16
Example 1 Step 1 Divide the tens. Can 8 tens be divided among 6? Yes – 6 2 Step 2 Bring down the ones. Divide the ones. Can 24 ones be divided among 6? Yes – – 0 Divide: 8 ÷ 6 Multiply: 1 × 6 Subtract: 8 – 6 Compare: 2 < 6 Divide: 24 ÷ 6 Multiply: 4 × 6 Subtract: 24 – 24 Compare: 0 < 6
Example 1 Answer: So, 84 carrot muffins will fit in 14 boxes. This is close to the estimate, 16. So, the answer is reasonable.

Example 2 Divide by a One-Digit Number Find Estimate 648 ÷ ÷ 3 = 200 Step 1 Divide the hundreds – ÷ 3 2 × 3 6 – 6 0 < 3
Example 2 Divide by a One-Digit Number Step 2 Bring down the tens. Divide the tens. 4 ÷ 3 1 × 3 4 – 3 1 < – – Step 3 Bring down the ones. Divide the ones. 18 ÷ 3 6 × 3 18 – 18 0 < – – –
Example 2 Divide by a One-Digit Number Answer: So, the quotient is 216.

Example 3 Division with a Remainder Find 139 ÷ 4. Estimate 139 ÷ ÷ 4 = 30 Step 1 Divide the hundreds Can 1 hundred be divided among 4? No. So, the first digit will be in the tens place.
Example 3 Division with a Remainder Step 2 Divide the tens. 13 ÷ 4 3 × 4 13 – 12 1 < – Step 3 Bring down the ones. Divide the ones. 19 ÷ 4 4 × 4 19 – 16 3 < – – 3 R3 There are no digits left to divide, so 3 is the remainder.
Example 3 Division with a Remainder Answer: The quotient is 34 R3.
1.A 2.B 3.C 4.D Example 3 A.21 R2 B.23 R3 C.28 R7 D.29 R2 Find 147 ÷ 5.
