We're dividing 91082009 by 172 
Our goal is to divide 91082009 by 172.

Advancing to step 1:
When dividing 9 by 172, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 172

Advancing to step 2:
The number 172 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 172

Going ahead to step 3:
If we divide 910 by 172, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 50 after subtracting 860 from 910.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 172

On to step 4:
The number 172 fits into 508 2 times, leaving a remainder of 164.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 344 from 508, we get 164.
Append the next digit (2) from the dividend to 164 and continue with: 1642 / 172

Going ahead to step 5:
If we divide 1642 by 172, we get 9 and a remainder of 94.
The number 9 becomes the next digit in our result. 
Result so far: 529.0
Deduct 1548 from 1642 and we're left with 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 172

Let's proceed to step 6:
172 can be fit into 940 5 times, resulting in a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 5295.0
Deduct 860 from 940 and we're left with 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 172

Step 7:
The number 172 fits into 800 4 times, leaving a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 52954.0
Subtracting 688 from 800 leaves us with 112.
Bring next digit (9) of the dividend behind the 112 and repeat the process: 1129 / 172

Moving on to step 8:
172 can be fit into 1129 6 times, resulting in a remainder of 97.
Use 6 as the next digit of our solution. 
Result so far: 529546.0
Deduct 1032 from 1129 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 9:
970 divided by 172 is 5 with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 529546.5
Subtracting 860 from 970 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
1100 divided by 172 is 6 with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 529546.56
Deduct 1032 from 1100 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
680 divided by 172 is 3 with a remainder of 164.
Record the quotient 3 as the next digit in the result. 
Result so far: 529546.563
Subtracting 516 from 680 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 12:
172 goes into 1640 9 times with a remainder of 92.
Record the quotient 9 as the next digit in the result. 
Result so far: 529546.5639
Deduct 1548 from 1640 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 13:
172 can be fit into 920 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 529546.56395
Subtract 860 from 920 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
172 can be fit into 600 3 times, resulting in a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 529546.563953
Subtract 516 from 600 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 15:
The number 172 fits into 840 4 times, leaving a remainder of 152.
The next digit of our result is 4. 
Result so far: 529546.5639534
The remainder is 152 after subtracting 688 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 16:
The number 172 fits into 1520 8 times, leaving a remainder of 144.
Record the quotient 8 as the next digit in the result. 
Result so far: 529546.56395348
If we take 1376 away from 1520, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

In conclusion, the division gives 529546.56395348 with a balance of 1.44e-07.
