9. After you bring down, you start the donut process all over again.

10. D 22 -6
new dividend
8 / 3 = 2 r2

11. M 22 -6 08 6
2 x 3 = 6

12. S -6 08 2
8 – 6 = 2

13. Br -6 08 25

14. Start the donut process again.

15. D 228 -6 08
new dividend
25 / 3 = 8 r1

16. M -6 08 25 24
8 x 3 = 24

17. S -6 08 25
- 24 1
25 – 24 = 1

18. Br 228 -6 08 25 - 24 1 3 685 There isn’t another number to bring down. -6 08 25
- 24 1
There isn’t another number to bring down.
The number left is less than the divisor.
So, the one becomes a remainder.

19. Br r1 -6 08 25
- 24 1
And you are done.

20. How can you check your answer?
Multiply the quotient by the divisor, then add in the remainder. It should add up to the dividend.
