Frequently asked questions
▶What is long division?
Long division is a step-by-step way to divide a big number by a small one. You divide, multiply, subtract, and bring down. The answer is the quotient, and the leftover is the remainder.
▶How do I use the long division lab?
Pick a 3-digit dividend and a 1-digit divisor using the sliders. The lab does each step on screen and shows the quotient and remainder. Watch the digits come down one by one.
▶When do we use long division?
Sharing 245 sweets among 5 cousins evenly, or splitting a 360-rupee electricity bill among 4 flats uses long division. Whenever the total is big, long division is your friend.
▶Tip for long division
Always check: quotient times divisor plus remainder should equal the original number. So for 245 divided by 5: 49 times 5 plus 0 equals 245. This check catches mistakes fast.
