We're dividing 88100974 by 172 
Our goal is to divide 88100974 by 172.

Let's proceed to step 1:
If we divide 8 by 172, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 172

Let's proceed to step 2:
If we divide 88 by 172, we get 0 and a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 172

Advancing to step 3:
The number 172 fits into 881 5 times, leaving a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 860 from 881 leaves us with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 172

On to step 4:
210 divided by 172 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
Subtracting 172 from 210 leaves us with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 172

Step 5:
The number 172 fits into 380 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 512.0
Subtract 344 from 380 to get 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 172

On to step 6:
If we divide 369 by 172, we get 2 and a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 5122.0
Subtracting 344 from 369 leaves us with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 172

Let's proceed to step 7:
When dividing 257 by 172, we get 1 with a remainder of 85.
The next digit of our result is 1. 
Result so far: 51221.0
Subtracting 172 from 257 leaves us with 85.
Append the next digit (4) from the dividend to 85 and continue with: 854 / 172

Moving on to step 8:
854 divided by 172 is 4 with a remainder of 166.
The number 4 becomes the next digit in our result. 
Result so far: 512214.0
Deduct 688 from 854 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
The number 172 fits into 1660 9 times, leaving a remainder of 112.
Record the quotient 9 as the next digit in the result. 
Result so far: 512214.9
If we subtract 1548 from 1660, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
If we divide 1120 by 172, we get 6 and a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 512214.96
If we subtract 1032 from 1120, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
The number 172 fits into 880 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 512214.965
Subtract 860 from 880 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
The number 172 fits into 200 1 times, leaving a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 512214.9651
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
The number 172 fits into 280 1 times, leaving a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 512214.96511
If we subtract 172 from 280, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

In conclusion, the division gives 512214.96511 with a balance of 0.000108.
