We're dividing 23515 by 88 
We want to figure out the number of times 23515 can be divided by 88.

Advancing to step 1:
2 divided by 88 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 88

Going ahead to step 2:
23 divided by 88 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 88

Moving on to step 3:
235 divided by 88 is 2 with a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 176 from 235, we get 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 88

Step 4:
88 can be fit into 591 6 times, resulting in a remainder of 63.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 528 away from 591, we end up with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 88

Step 5:
88 goes into 635 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 267.0
The remainder is 19 after subtracting 616 from 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 6:
The number 88 fits into 190 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 267.2
The remainder is 14 after subtracting 176 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
88 goes into 140 1 times with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 267.21
If we subtract 88 from 140, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
If we divide 520 by 88, we get 5 and a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 267.215
Deduct 440 from 520 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
88 goes into 800 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 267.2159
Subtract 792 from 800 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
88 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 267.2159
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
If we divide 800 by 88, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 267.215909
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 88 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 267.215909
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
88 goes into 800 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 267.21590909
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 267.21590909, with a leftover of 8e-09.
