We divide 172813 by 12
Let's see how many times 12 fits into 172813.

Advancing to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 12

Advancing to step 2:
12 can be fit into 17 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 12 from 17, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 12

On to step 3:
If we divide 52 by 12, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 48 from 52 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 12

Going ahead to step 4:
If we divide 48 by 12, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 144.0
Subtract 48 from 48 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 12

Going ahead to step 5:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1440.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 12

Step 6:
12 goes into 13 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 14401.0
If we subtract 12 from 13, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 12 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 14401.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
12 goes into 100 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 14401.08
Subtracting 96 from 100 leaves us with 4.
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 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 14401.083
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 14401.0833
Subtract 36 from 40 to 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.

The final result is 14401.0833 with a remainder of 4e-05.
