815040 divided by 99 
Let's see how many times 99 fits into 815040.

Advancing to step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 99

On to step 2:
If we divide 81 by 99, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 99

Going ahead to step 3:
815 divided by 99 is 8 with a remainder of 23.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 792 from 815 leaves us with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 99

Advancing to step 4:
The number 99 fits into 230 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
The remainder is 32 after subtracting 198 from 230.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 99

On to step 5:
99 can be fit into 324 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 823.0
Subtracting 297 from 324 leaves us with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 99

On to step 6:
99 can be fit into 270 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 8232.0
The remainder is 72 after subtracting 198 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 7:
When dividing 720 by 99, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 8232.7
Subtract 693 from 720 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 8:
When dividing 270 by 99, we get 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 8232.72
If we take 198 away from 270, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
If we divide 720 by 99, we get 7 and a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 8232.727
If we take 693 away from 720, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
When dividing 270 by 99, we get 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 8232.7272
Subtracting 198 from 270 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
99 goes into 720 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 8232.72727
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
99 goes into 270 2 times with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 8232.727272
If we subtract 198 from 270, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
720 divided by 99 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 8232.7272727
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
270 divided by 99 is 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 8232.72727272
Subtracting 198 from 270 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 8232.72727272 and a remainder of 7.2e-08.
