What is Division?
Splitting into equal parts
Division is one of the four basic arithmetic operations. When you divide, you find how many times one number fits into another. The result is the quotient. Sometimes there is a remainder—the amount left over when the divisor does not divide evenly. For example, 17 ÷ 5 = 3 remainder 2.
Exact Division
When the dividend is evenly divisible by the divisor, the quotient is a whole number with no remainder.
Practice Division →Division with Remainder
When division is not exact, we express the remainder as "q r r"—e.g., 17 ÷ 5 = 3 r 2. Use our remainder mode to practice.

Key steps for dividing whole numbers
Long Division
Divide digit by digit from left to right. Subtract, bring down, repeat until you reach the ones place or a remainder.
Remainder
The remainder is what is left when the divisor does not divide evenly. It is always less than the divisor.

Why Division Matters
Division helps you split quantities fairly, find rates, and solve proportion problems. Remainders appear in real-world situations like sharing items.
Applications
Used in sharing, rates, ratios, averages, and any situation where you split a quantity into equal parts.
