We're dividing 12630 by 88 
Our goal is to divide 12630 by 88.

Advancing to step 1:
1 divided by 88 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 88

On to step 2:
The number 88 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 88

On to step 3:
If we divide 126 by 88, we get 1 and a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 88 from 126 leaves us with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 88

Advancing to step 4:
The number 88 fits into 383 4 times, leaving a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 31 after subtracting 352 from 383.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 88

Step 5:
88 goes into 310 3 times with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 143.0
If we subtract 264 from 310, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 6:
88 can be fit into 460 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 143.5
If we subtract 440 from 460, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 88 fits into 200 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 143.52
If we subtract 176 from 200, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
240 divided by 88 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 143.522
If we subtract 176 from 240, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 143.522 and a remainder of 0.0064.
