We're dividing 398923 by 88 
We want to divide 398923 by 88.

On to step 1:
When dividing 3 by 88, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 88

On to step 2:
88 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 88

Going ahead to step 3:
88 can be fit into 398 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 352 from 398 leaves us with 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 88

Step 4:
88 goes into 469 5 times with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 440 away from 469, we end up with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 88

Going ahead to step 5:
When dividing 292 by 88, we get 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 453.0
Deduct 264 from 292 and we're left with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 88

Let's proceed to step 6:
When dividing 283 by 88, we get 3 with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 4533.0
The remainder is 19 after subtracting 264 from 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 88 fits into 190 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 4533.2
Subtracting 176 from 190 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
140 divided by 88 is 1 with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 4533.21
Deduct 88 from 140 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
88 goes into 520 5 times with a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 4533.215
Subtracting 440 from 520 leaves us 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.

On to step 10:
800 divided by 88 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4533.2159
Deduct 792 from 800 and we're left 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.

Going ahead to step 11:
80 divided by 88 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 4533.2159
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.

Going ahead to step 12:
88 goes into 800 9 times with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4533.215909
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.

On to step 13:
88 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 4533.215909
Subtract 0 from 80 to 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.

On to step 14:
800 divided by 88 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 4533.21590909
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.

The final outcome is 4533.21590909, with a leftover of 8e-09.
