Mastering Long Division with Double Digit Divisors

This video tutorial covers long division with two-digit divisors, emphasizing the need for estimation and trial and error. The instructor provides examples, such as dividing 756 by 18 and 2668 by 46, to demonstrate the process. The tutorial concludes with a preview of the next episode, which will focus on division with decimal divisors.

What is the primary reason for needing more thought when dividing with two-digit divisors?

• To estimate and round numbers effectively

• To simplify the division process

• To handle larger numbers

• To use advanced mathematical formulas
