Question 1

How does long division work?

Accepted Answer

Long division works by repeatedly dividing the divisor into portions of the dividend, starting from the leftmost digits. At each step, you determine how many times the divisor fits, multiply to find the product, subtract to get the remainder, then bring down the next digit. This process continues until all digits have been processed.

Question 2

What is the difference between quotient and remainder?

Accepted Answer

The quotient is the whole number result of a division, representing how many complete times the divisor fits into the dividend. The remainder is the amount left over. For example, 17 divided by 5 gives a quotient of 3 and a remainder of 2, because 5 x 3 = 15 and 17 - 15 = 2.

Question 3

Can you have a negative remainder?

Accepted Answer

In standard mathematical convention, the remainder is typically non-negative and less than the absolute value of the divisor. However, in programming languages like JavaScript, the remainder can be negative when the dividend is negative. This calculator uses truncated division, which preserves the sign of the dividend in the remainder.

Question 4

How do I convert a division result to a mixed number?

Accepted Answer

A mixed number combines a whole number and a fraction. After dividing, the quotient becomes the whole number part, and the remainder over the divisor becomes the fractional part. For example, 23 / 4 = 5 remainder 3, so the mixed number is 5 and 3/4.

Question 5

How can I verify my division is correct?

Accepted Answer

Use the verification formula: Quotient x Divisor + Remainder = Dividend. If this equation holds, your division is correct. For example, if 47 / 6 = 7 remainder 5, check: 7 x 6 + 5 = 42 + 5 = 47. Since this equals the dividend, the answer is verified.
