We divide 508172 by 12
Our goal is to divide 508172 by 12.

On to step 1:
5 divided by 12 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

Step 2:
When dividing 50 by 12, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 48 from 50 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

Going ahead to step 3:
When dividing 28 by 12, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 42.0
If we take 24 away from 28, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 12

Moving on to step 4:
12 goes into 41 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
Subtracting 36 from 41 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Moving on to step 5:
12 goes into 57 4 times with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4234.0
The remainder is 9 after subtracting 48 from 57.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 12

Let's proceed to step 6:
The number 12 fits into 92 7 times, leaving a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 42347.0
Subtract 84 from 92 to 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.

On to step 7:
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: 42347.6
Deduct 72 from 80 and we're left 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.

Moving on to step 8:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 42347.66
Subtract 72 from 80 to 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.

In conclusion, the division gives 42347.66 with a balance of 0.008.
