Going ahead to step 1:
88 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 88

Step 2:
If we divide 81 by 88, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 88

Let's proceed to step 3:
88 goes into 815 9 times with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 792 from 815 and we're left with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 88

Moving on to step 4:
231 divided by 88 is 2 with a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 92.0
Subtract 176 from 231 to get 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 88

Moving on to step 5:
The number 88 fits into 559 6 times, leaving a remainder of 31.
The next digit of our result is 6. 
Result so far: 926.0
Deduct 528 from 559 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 88

On to step 6:
The number 88 fits into 319 3 times, leaving a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 9263.0
The remainder is 55 after subtracting 264 from 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
When dividing 550 by 88, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 9263.6
If we subtract 528 from 550, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
When dividing 220 by 88, we get 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 9263.62
If we subtract 176 from 220, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
440 divided by 88 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9263.625
Subtract 440 from 440 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
88 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9263.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
88 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9263.625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 9263.625 with a remaining 0.0.
