Teacher notes
- Decimals are scaled to whole numbers before the long-division loop; every subtraction and remainder is logged for projection.
- Long multiplication records each partial product with carries so you can narrate digit-by-digit.
FAQ
How does the calculator detect repeating decimals?
We store each remainder while generating decimal digits. When a remainder repeats, we mark the repeating digits and show parentheses around them.
What controls the number of decimal digits in long division?
Use the max decimal digits field to set the precision (default 20). If the remainder persists after hitting the limit, we also show the remainder as a fraction of the scaled divisor.
