That interpretation doesn’t make sense. Repeated subtraction does not correspond to division in the way repeated addition corresponds to multiplication.

- simondotau 8d agoThis isn’t analogous to repeated addition giving multiplication. You’ve switched from applying an operation nine times to counting how many times an operation can be applied. You chose 81 because it’s the one number that makes your argument appear to work. Try the same reasoning with 80 ÷ 9.
