990839 ÷ 88 
We want to divide 990839 by 88.

Moving on to step 1:
88 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 88

On to step 2:
When dividing 99 by 88, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 88 from 99, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 88

Going ahead to step 3:
When dividing 110 by 88, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 88 away from 110, we end up with 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 88

Step 4:
228 divided by 88 is 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
The remainder is 52 after subtracting 176 from 228.
Include the next digit (3) from the dividend after 52, then repeat: 523 / 88

Step 5:
If we divide 523 by 88, we get 5 and a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 1125.0
Subtracting 440 from 523 leaves us with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 88

Advancing to step 6:
88 can be fit into 839 9 times, resulting in a remainder of 47.
The next digit of our result is 9. 
Result so far: 11259.0
If we subtract 792 from 839, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
When dividing 470 by 88, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 11259.5
The remainder is 30 after subtracting 440 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
88 can be fit into 300 3 times, resulting in a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 11259.53
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
The number 88 fits into 360 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11259.534
If we take 352 away from 360, 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 10:
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: 11259.534
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 11:
88 can be fit into 800 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 11259.53409
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.

Moving on to step 12:
88 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 11259.53409
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.

Going ahead to step 13:
The number 88 fits into 800 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 11259.5340909
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 14:
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: 11259.5340909
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.

The final result is 11259.5340909 with a remainder of 8e-08.
