Attached file is a picture of the long division in steps.
i) 18 goes into 56, the answer is 3.
3 times 18 gives 54. 56 subtract 54. That gives 2.
ii) Bring down the 3. So we have a new number 23.
iii) 18 into 23. That is 1.
1 times 18 gives 18. 23 subtract 18. That gives 5.
iv) Bring down the 4. So we have a new number 54.
18 inot 54. That is 3.
3 times 18 also gives 54. 54 subtract 54. That is nothing.
v) So the answer is 313. Cheers.
