如何计算Long Division
learn.whatIsHeading
Long division is a step-by-step method for dividing large numbers by hand. It breaks the division into a sequence of smaller operations — divide, multiply, subtract, bring down — repeated until the calculation is complete. The result is a quotient and (optionally) a remainder.
分步指南
- 1Write the dividend inside the bracket and the divisor outside
- 2Divide the first digit(s) of the dividend by the divisor to get the first quotient digit
- 3Multiply that quotient digit by the divisor and write the product below
- 4Subtract to find the remainder, then bring down the next digit
- 5Repeat steps 2–4 until all digits are processed
