6.07 Divide decimals by 2 digit numbers

Lesson

Are you ready?

Do you remember how to use the division algorithm for dividing without remainders? Let's try this problem to practice.

Find the value of $744\div8$744÷​8.

Learn

This video shows how we can use long division to divide numbers with decimals, the same way that we would for whole numbers. It also shows how we can use estimation to check the position of the decimal point.

Question

Find the value of $68.4\div6$68.4÷​6.

 

Remember!

When we are dividing, we always start with the digit that is farthest to the left, then continue to divide each digit to the right moving across the decimal to units, tenths and so on if necessary.

The place values of the number being divided and the result of the division should line up.

 

Outcomes

5.NBT.B.7

Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between operations. Assess the reasonableness of answers using estimation strategies. (Limit multiplication problems so that the product does not exceed thousandths. Limit division problems so that either the dividend or the divisor is a whole number.)
