Let's divide 802171 by 99
We're looking to find how many times 99 goes into 802171.

Step 1:
99 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 99

On to step 2:
80 divided by 99 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 99

Let's proceed to step 3:
When dividing 802 by 99, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 792 from 802 and we're left with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 99

Moving on to step 4:
101 divided by 99 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtract 99 from 101 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 99

Moving on to step 5:
27 divided by 99 is 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 810.0
If we take 0 away from 27, we end up with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 99

Moving on to step 6:
99 can be fit into 271 2 times, resulting in a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 8102.0
If we subtract 198 from 271, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
99 goes into 730 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 8102.7
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
370 divided by 99 is 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 8102.73
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
The number 99 fits into 730 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 8102.737
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
99 goes into 370 3 times with a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 8102.7373
Deduct 297 from 370 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 11:
If we divide 730 by 99, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 8102.73737
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
370 divided by 99 is 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 8102.737373
The remainder is 73 after subtracting 297 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 13:
99 goes into 730 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 8102.7373737
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
When dividing 370 by 99, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 8102.73737373
If we subtract 297 from 370, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

After the division, we end up with 8102.73737373 and a remainder of 7.3e-08.
