Mastering Long Division with Decimals

This video tutorial from ajspeller.com covers long division using the standard method. It includes three examples with different divisors and dividends, demonstrating how to write quotients as decimals and round them to the nearest hundredths. The tutorial uses a mnemonic 'Does McDonald's Sell Burgers' to help remember the steps: Divide, Multiply, Subtract, and Bring down. Each example is solved step-by-step, with explanations on handling decimals and rounding. The video concludes with a summary of the solutions and verification of the results.
