We look at the division of 57821664 by 172 
We want to figure out the number of times 57821664 can be divided by 172.

Step 1:
5 divided by 172 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 172

Going ahead to step 2:
57 divided by 172 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 172

Let's proceed to step 3:
578 divided by 172 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 516 from 578 and we're left with 62.
Bring next digit (2) of the dividend behind the 62 and repeat the process: 622 / 172

On to step 4:
When dividing 622 by 172, we get 3 with a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtract 516 from 622 to get 106.
Grab the next digit (1) from the dividend, add it to 106, then carry on: 1061 / 172

Step 5:
172 can be fit into 1061 6 times, resulting in a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 336.0
If we subtract 1032 from 1061, we get 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 172

Let's proceed to step 6:
If we divide 296 by 172, we get 1 and a remainder of 124.
The next digit of our result is 1. 
Result so far: 3361.0
Deduct 172 from 296 and we're left with 124.
Take the next digit (6) from the dividend and append it to 124, then repeat: 1246 / 172

Going ahead to step 7:
172 can be fit into 1246 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 33617.0
Subtracting 1204 from 1246 leaves us with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 172

On to step 8:
172 can be fit into 424 2 times, resulting in a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 336172.0
The remainder is 80 after subtracting 344 from 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
172 can be fit into 800 4 times, resulting in a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 336172.4
Deduct 688 from 800 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 10:
If we divide 1120 by 172, we get 6 and a remainder of 88.
The next digit of our result is 6. 
Result so far: 336172.46
If we take 1032 away from 1120, we end up with 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:
880 divided by 172 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 336172.465
Deduct 860 from 880 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
If we divide 200 by 172, we get 1 and a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 336172.4651
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
172 can be fit into 280 1 times, resulting in a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 336172.46511
If we take 172 away from 280, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 336172.46511 and a remainder of 0.000108.
