Answer:
5 Remainder 3
Explanation:
To do division in this form, you have to look at the number on the side (8) and see if it can go into the first number, 4. It cannot, so we add the second digit next to four, 43. Can 8 fit into 43? Yes it can, but it will have a remainder.
When you do the math, you figure out that 8 can go into 40 five times. Write five in that first box above, and write 40 under 43 (because this is the amount of numbers you took out of 43). Subract those two numbers and you get 3.
Thus, the remainder is 3.
