Understanding Long Division with Large Numbers
What You'll Learn: How to divide very large numbers (like 45,678 or 234,567) by two-digit numbers (like 23 or 87) and three-digit numbers (like 145 or 328) using the long division algorithm.
The Long Division Structure
Long division is like a step-by-step recipe for dividing big numbers. Let's look at how it's organized:
The Four-Step Process: DMSB
Remember these four steps - they repeat over and over:
D
Divide
How many times does the divisor fit into the current digits?
M
Multiply
Multiply your answer by the divisor to check.
S
Subtract
Subtract to find what's left over.
B
Bring Down
Bring down the next digit and repeat!
