We look at the division of 172857 by 68 
Let's see how many times 68 fits into 172857.

Step 1:
If we divide 1 by 68, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 68

On to step 2:
68 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 68

Step 3:
If we divide 172 by 68, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 136 from 172 and we're left with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 68

On to step 4:
68 goes into 368 5 times with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 340 from 368, we get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 68

On to step 5:
68 can be fit into 285 4 times, resulting in a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
Subtracting 272 from 285 leaves us with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 68

On to step 6:
The number 68 fits into 137 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2542.0
Deduct 136 from 137 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 68 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2542.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
68 goes into 100 1 times with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 2542.01
Deduct 68 from 100 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
68 can be fit into 320 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 2542.014
If we subtract 272 from 320, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
When dividing 480 by 68, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 2542.0147
If we subtract 476 from 480, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
The number 68 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2542.0147
The remainder is 40 after subtracting 0 from 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 12:
If we divide 400 by 68, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 2542.014705
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
68 can be fit into 600 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 2542.0147058
Deduct 544 from 600 and we're left 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.

Advancing to step 14:
The number 68 fits into 560 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2542.01470588
The remainder is 16 after subtracting 544 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 2542.01470588 and a remainder of 1.6e-08.
