Decimal Division with Partial Quotients

This video tutorial covers the division of decimals using the partial quotients method. It begins with an introduction to the concept and proceeds with three examples: dividing 16.20 by 4, 119.6 by 23, and 0.648 by 0.9. Each example demonstrates the step-by-step process, including how to handle decimals and align them correctly in the final answer. The tutorial emphasizes the importance of ignoring decimals during calculations and adjusting them at the end to ensure accurate results.

What is the first step when dividing decimals using the partial quotients method?

• Multiply both numbers by 10.

• Subtract the smaller number from the larger number.

• Ignore the decimal point initially.

• Move the decimal point in the divisor.
