We divide 397988 by 88
We want to divide 397988 by 88.

On to step 1:
The number 88 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 88

Going ahead to step 2:
The number 88 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 88

Step 3:
397 divided by 88 is 4 with a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 352 from 397 leaves us with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 88

Step 4:
88 can be fit into 459 5 times, resulting in a remainder of 19.
The next digit of our result is 5. 
Result so far: 45.0
Deduct 440 from 459 and we're left with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 88

Step 5:
The number 88 fits into 198 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 452.0
Deduct 176 from 198 and we're left with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 88

On to step 6:
If we divide 228 by 88, we get 2 and a remainder of 52.
The next digit of our result is 2. 
Result so far: 4522.0
The remainder is 52 after subtracting 176 from 228.
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 7:
520 divided by 88 is 5 with a remainder of 80.
The next digit of our result is 5. 
Result so far: 4522.5
The remainder is 80 after subtracting 440 from 520.
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 8:
If we divide 800 by 88, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4522.59
Subtracting 792 from 800 leaves us 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 9:
The number 88 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4522.59
Subtracting 0 from 80 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:
If we divide 800 by 88, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4522.5909
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.

Step 11:
If we divide 80 by 88, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4522.5909
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.

Let's proceed 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: 4522.590909
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.

Step 13:
If we divide 80 by 88, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4522.590909
The remainder is 80 after subtracting 0 from 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:
88 goes into 800 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 4522.59090909
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.

The final outcome is 4522.59090909, with a leftover of 8e-09.
