  3. Click the "Calculate" button to see the result.
  4. Review the step-by-step solution provided below the result.

The calculator handles both positive and negative numbers correctly, following standard mathematical rules for signed division.

Long Division Method

Long division is a method for dividing numbers that involves a series of steps to find the quotient and remainder. Here's how it works:

  1. Divide the first part of the dividend by the divisor to get the first digit of the quotient.
  2. Multiply this digit by the divisor and subtract the result from the first part of the dividend to get the remainder.
  3. Bring down the next digit of the dividend and repeat the process.
  4. Continue until you've brought down all digits of the dividend.

Formula

For any two numbers A (dividend) and B (divisor), the division can be expressed as:

A ÷ B = Quotient + (Remainder ÷ B)

When dealing with negative numbers, remember that:

  • A positive divided by a negative is negative.
  • A negative divided by a positive is negative.
  • A negative divided by a negative is positive.

Worked Examples

Example 1: Positive Numbers

Divide 144 by 12:

  1. 12 goes into 14 once (1 × 12 = 12). Subtract 12 from 14 to get 2.
  2. Bring down the 4 to make 24.
  3. 12 goes into 24 twice (2 × 12 = 24). Subtract 24 from 24 to get 0.

The result is 12 with a remainder of 0.

Example 2: Negative Numbers

Divide -144 by 12:

  1. 12 goes into 14 once (1 × 12 = 12). Subtract 12 from 14 to get 2.
  2. Bring down the 4 to make 24.
  3. 12 goes into 24 twice (2 × 12 = 24). Subtract 24 from 24 to get 0.

The result is -12 with a remainder of 0.

Tip

When dividing negative numbers, the sign of the result depends on the signs of the dividend and divisor. Remember the rule: negative divided by negative is positive.

FAQ
