Dividing Decimals: Step-by-Step Techniques

The video tutorial explains how to divide decimals, starting with an example of dividing 31.77575 by 5.1. The instructor emphasizes the importance of removing the decimal from the divisor by shifting it to the right and doing the same for the dividend. This adjustment allows for normal long division to be performed. The tutorial walks through the division process step-by-step, including placing the decimal point in the quotient. The final answer is 6.23. The video concludes with a mention of additional resources for further practice.

What is the first step in setting up a division problem involving decimals?

• Set up the problem using long division

• Multiply both numbers by 10
