90 divided by 9 is 10

so you can subtract 9 from 90 for 10 times before you reach 0

if you want to go into negative numbers you can keep subtracting as many times as you like

you are sooooooooo wrong WOW. You can subtract 9 once from 90 because once you subtract 9 from 90, 90 becomes 81. That's how I do it
