We look at the division of 99171941 by 172 
We want to divide 99171941 by 172.

Step 1:
9 divided by 172 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 172

Moving on to step 2:
99 divided by 172 is 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 172

Going ahead to step 3:
The number 172 fits into 991 5 times, leaving a remainder of 131.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 860 from 991 to get 131.
Append the next digit (7) from the dividend to 131 and continue with: 1317 / 172

Let's proceed to step 4:
When dividing 1317 by 172, we get 7 with a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Subtracting 1204 from 1317 leaves us with 113.
Grab the next digit (1) from the dividend, add it to 113, then carry on: 1131 / 172

Moving on to step 5:
When dividing 1131 by 172, we get 6 with a remainder of 99.
Record the quotient 6 as the next digit in the result. 
Result so far: 576.0
The remainder is 99 after subtracting 1032 from 1131.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 172

Advancing to step 6:
172 can be fit into 999 5 times, resulting in a remainder of 139.
The number 5 becomes the next digit in our result. 
Result so far: 5765.0
If we take 860 away from 999, we end up with 139.
Grab the next digit (4) from the dividend, add it to 139, then carry on: 1394 / 172

Moving on to step 7:
If we divide 1394 by 172, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 57658.0
Subtract 1376 from 1394 to get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 172

Going ahead to step 8:
When dividing 181 by 172, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 576581.0
If we take 172 away from 181, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
172 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 576581.0
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
If we divide 900 by 172, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 576581.05
If we subtract 860 from 900, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
The number 172 fits into 400 2 times, leaving a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 576581.052
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
172 goes into 560 3 times with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 576581.0523
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
172 goes into 440 2 times with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 576581.05232
Subtract 344 from 440 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
The number 172 fits into 960 5 times, leaving a remainder of 100.
The next digit of our result is 5. 
Result so far: 576581.052325
The remainder is 100 after subtracting 860 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
When dividing 1000 by 172, we get 5 with a remainder of 140.
The next digit of our result is 5. 
Result so far: 576581.0523255
Subtracting 860 from 1000 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 576581.0523255 with a remaining 1.4e-06.
