使用方法

长除法每次处理一位数字：把下一位数字拿下来，看看除数能被容纳多少次，做减法，并将余数带入下一列。

当被除数无法容纳除数时，商的该位数字为0，且这个0仍必须写出来——这是学生最常漏掉数字的地方。

对于负数，商会向零方向截断，余数的符号与被除数一致，因此“除数 × 商 + 余数”始终等于被除数。

Tips & Common Mistakes

Tips

Ensure both numbers are whole numbers; the calculator is designed for integer division.
Use the step-by-step tableau to trace each bring-down and subtraction, which reinforces your understanding.
Check the decimal answer to see the exact result when the division does not end evenly.
Use the remainder to verify your manual calculations or to understand non-terminating divisions.

Common Mistakes to Avoid

Forgetting that the divisor cannot be zero; division by zero is undefined.
Misinterpreting the remainder as the final answer when the decimal answer is also provided.
Skipping the step-by-step tableau and only looking at the final quotient, missing the learning opportunity.
