Let's divide 399000 by 88
We want to figure out the number of times 399000 can be divided by 88.

Step 1:
88 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 88

Let's proceed to step 2:
The number 88 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 88

Let's proceed to step 3:
The number 88 fits into 399 4 times, leaving a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 352 from 399 leaves us with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 88

Advancing to step 4:
When dividing 470 by 88, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 440 from 470, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 88

Let's proceed to step 5:
When dividing 300 by 88, we get 3 with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 453.0
If we subtract 264 from 300, we get 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 88

Going ahead to step 6:
88 goes into 360 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4534.0
Subtracting 352 from 360 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.

Advancing to step 7:
When dividing 80 by 88, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4534.0
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.

Advancing to step 8:
When dividing 800 by 88, we get 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 4534.09
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 9:
If we divide 80 by 88, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 4534.09
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.

Moving on to step 10:
If we divide 800 by 88, we get 9 and a remainder of 8.
The next digit of our result is 9. 
Result so far: 4534.0909
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.

Step 11:
88 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4534.0909
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.

On to step 12:
The number 88 fits into 800 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 4534.090909
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.

Going ahead to step 13:
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: 4534.090909
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.

Going ahead to step 14:
When dividing 800 by 88, we get 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 4534.09090909
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 result is 4534.09090909 with a remainder of 8e-09.
