Mastering 3-Digit by 1-Digit Long Division with Remainders

Mr. W introduces long division, explaining how to divide larger numbers into smaller, equal groups using long division brackets. The lesson covers key vocabulary such as dividend, divisor, and quotient, and outlines the five main steps: divide, multiply, subtract, bring down, and repeat. Two example problems are solved step-by-step, demonstrating the process and handling remainders. The video concludes with encouragement to practice the steps independently.

What is the purpose of long division?

• To find the square root of a number
