Answer:
6 goes into 8, 1 time therefore the top of the bar would be 1.
6 subtracted from 8 would be 2 so 2 would be at the first bottom blank space under the bar.
Since 6 goes into 24, 4 times you would put 4 on the top of the bar which is already filled in, multiply them again and place 24 under the other 24 under the bar and subtract 24 from 24 to get 0.
