We look at the division of 173013 by 12 
We're looking to find how many times 12 goes into 173013.

Going ahead to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 12

Advancing 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
Subtracting 12 from 17 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 12

Moving on to step 3:
12 goes into 53 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 48 away from 53, we end up with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 12

Moving on to step 4:
The number 12 fits into 50 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
If we take 48 away from 50, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 12

Going ahead to step 5:
If we divide 21 by 12, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1441.0
The remainder is 9 after subtracting 12 from 21.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 12

Let's proceed to step 6:
The number 12 fits into 93 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 14417.0
Subtract 84 from 93 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
When dividing 90 by 12, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 14417.7
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14417.75
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14417.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14417.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 14417.75 and a remainder of 0.0.
