Let's divide 503185 by 12
We want to figure out the number of times 503185 can be divided by 12.

On to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

Going ahead to step 2:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 48 from 50 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Let's proceed to step 3:
12 can be fit into 23 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 12 from 23 to get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 12

Let's proceed to step 4:
111 divided by 12 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 419.0
If we take 108 away from 111, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 12

On to step 5:
12 can be fit into 38 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 4193.0
The remainder is 2 after subtracting 36 from 38.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 12

On to step 6:
25 divided by 12 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 41932.0
Subtract 24 from 25 to 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.

Moving on to step 7:
10 divided by 12 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 41932.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 41932.08
If we subtract 96 from 100, we 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.

Let's proceed to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 41932.083
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.

Going ahead to step 10:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 41932.0833
If we subtract 36 from 40, we 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.

Our division results in 41932.0833 with a remaining 4e-05.
