81749357 divided by 172 
Our goal is to divide 81749357 by 172.

Let's proceed to step 1:
The number 172 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 172

Advancing to step 2:
If we divide 81 by 172, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (7) of the dividend behind the 81 and repeat the process: 817 / 172

Step 3:
172 goes into 817 4 times with a remainder of 129.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 688 from 817 to get 129.
Grab the next digit (4) from the dividend, add it to 129, then carry on: 1294 / 172

Going ahead to step 4:
If we divide 1294 by 172, we get 7 and a remainder of 90.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 1204 from 1294 leaves us with 90.
Fetch the next digit (9) from the dividend, attach it to 90 and continue: 909 / 172

Moving on to step 5:
When dividing 909 by 172, we get 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 475.0
Subtracting 860 from 909 leaves us with 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 172

Let's proceed to step 6:
493 divided by 172 is 2 with a remainder of 149.
Write down 2 as next digit of the result. 
Result so far: 4752.0
The remainder is 149 after subtracting 344 from 493.
Fetch the next digit (5) from the dividend, attach it to 149 and continue: 1495 / 172

Going ahead to step 7:
When dividing 1495 by 172, we get 8 with a remainder of 119.
Use 8 as the next digit of our solution. 
Result so far: 47528.0
Subtracting 1376 from 1495 leaves us with 119.
Take the next digit (7) from the dividend and append it to 119, then repeat: 1197 / 172

Step 8:
The number 172 fits into 1197 6 times, leaving a remainder of 165.
Put 6 as the next digit of the answer. 
Result so far: 475286.0
The remainder is 165 after subtracting 1032 from 1197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 9:
When dividing 1650 by 172, we get 9 with a remainder of 102.
Write down 9 as next digit of the result. 
Result so far: 475286.9
Deduct 1548 from 1650 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
172 can be fit into 1020 5 times, resulting in a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 475286.95
Subtracting 860 from 1020 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
172 can be fit into 1600 9 times, resulting in a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 475286.959
Subtracting 1548 from 1600 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
If we divide 520 by 172, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 475286.9593
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
172 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 475286.9593
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
172 can be fit into 400 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 475286.959302
Subtracting 344 from 400 leaves us with 56.
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 15:
560 divided by 172 is 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 475286.9593023
If we subtract 516 from 560, we 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 16:
172 goes into 440 2 times with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 475286.95930232
If we subtract 344 from 440, we 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.

In conclusion, the division gives 475286.95930232 with a balance of 9.6e-08.
