3 1 time 2 times 3 times
with 3 left over Part of a whole... 1/2 or 0.5 What does dividing mean? What are decimals? This can be written a few different ways:

15 divided by 4

15 4

4 15

15
4 Whole # divided by Whole # Decimal divided by Whole # Whole # divided by Decimal Decimal divided by Decimal Step 1: Estimate what the quotient should be before solving. 3 6 How many times can we take 6 out of 3? Step 2: If the divisor if bigger than the dividend;
add a decimal in the dividend and write a zero. 3.0 6 Step 3: Bring your decimals straight up and divide like normal.
** There will not be remainders! 3.0 6 0. Step 1: Estimate what the quotient should be before solving. 34.4 2 2 34.4 How many times can we take 2 our of 34.4? Step 2: Bring your decimal STRAIGHT UP in your answer. 2 34.4 2 34.4

0 17 2 Step 3: Solve like normal.
(Remember to add zeros when
you get to the end of the number.) Step 1: Estimate how many times you can take 1.1 out of 24? 24 1.1 1.1 24 Step 2: Move the decimal in the divisor to the right
until it is a WHOLE NUMBER. 1.1 24 Step 3: What you do to the outside you
MUST do the SAME to the inside. 11. 24. What are we moving around? 24 = 24. = 24.0 = 24.000000 1.1 24.0 11 240.0 . Now divide like normal... Bring your decimal straight up. Let's Try It! 0.25 6 1.5 9 0.125 16 Step 1: Estimate what the quotient should be before solving. 26.34 0.4 Step 2: Move the decimal in the divisor until it is a whole number. 0.4 26.34 REMEMBER: What you do to the outside,
you do to the inside! Step 3: Move the decimal in the dividend the same amount. 0.4 26.34 Step 4: Move your decimal up to the quotient line and divide like normal. 4 263.4 . Let's Try It! 14.2 140 1.456 27.23 0.23 0.3 0 0 0 0 0 4 15 3 -12 3 3 3
