8512 ÷ 63 
Let's see how many times 63 fits into 8512.

Going ahead to step 1:
The number 63 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 63

On to step 2:
63 can be fit into 85 1 times, resulting in a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 63 away from 85, we end up with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 63

Going ahead to step 3:
63 goes into 221 3 times with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 32 after subtracting 189 from 221.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 63

Moving on to step 4:
The number 63 fits into 322 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 135.0
The remainder is 7 after subtracting 315 from 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 5:
If we divide 70 by 63, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 135.1
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 6:
The number 63 fits into 70 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 135.11
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 135.11 with a remaining 0.007.
