We look at the division of 174857 by 12 
We want to divide 174857 by 12.

Advancing to step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 12

On to step 2:
12 goes into 17 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 12 from 17 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 12

Step 3:
12 goes into 54 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 48 from 54, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 12

Step 4:
12 can be fit into 68 5 times, resulting in a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we take 60 away from 68, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 12

Step 5:
85 divided by 12 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 1457.0
If we subtract 84 from 85, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 12

On to step 6:
If we divide 17 by 12, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 14571.0
If we subtract 12 from 17, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 12 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 14571.4
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 12 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 14571.41
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 14571.416
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 14571.4166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 14571.4166 and a remainder of 8e-05.
