Zero-Removal Trick in Division

The video tutorial explains how to simplify division problems by using a trick involving zeros. It starts with dividing 700 by 70, showing how to express it as a fraction and simplify by removing zeros. The same method is applied to other problems like 300 divided by 10 and 9900 divided by 10, demonstrating how removing zeros from both the numerator and denominator simplifies the calculation. This technique is useful for quick division drills involving multiples of 10.
