Let's divide 517124 by 12
Our goal is to divide 517124 by 12.

On to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

Step 2:
12 can be fit into 51 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 48 from 51 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 12

Step 3:
12 can be fit into 37 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 1 after subtracting 36 from 37.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 12

Step 4:
If we divide 11 by 12, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 430.0
Subtract 0 from 11 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 12

Advancing to step 5:
12 goes into 112 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 4309.0
Subtracting 108 from 112 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 12

Let's proceed to step 6:
12 can be fit into 44 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 43093.0
The remainder is 8 after subtracting 36 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 43093.6
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.

Let's proceed to step 8:
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: 43093.66
Subtracting 72 from 80 leaves us 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.

After the division, we end up with 43093.66 and a remainder of 0.008.
