We're dividing 503452 by 12 
Our goal is to divide 503452 by 12.

Going ahead to step 1:
12 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 12

On to step 2:
When dividing 50 by 12, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 48 from 50 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 12

Moving on to step 3:
When dividing 23 by 12, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 12 from 23 to get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 12

Moving on to step 4:
12 can be fit into 114 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 419.0
The remainder is 6 after subtracting 108 from 114.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 12

Let's proceed to step 5:
12 can be fit into 65 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 4195.0
If we subtract 60 from 65, we get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 12

Moving on to step 6:
When dividing 52 by 12, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 41954.0
Deduct 48 from 52 and we're left 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.

Moving on to step 7:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 41954.3
If we take 36 away from 40, we end up 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.

Advancing to step 8:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 41954.33
If we take 36 away from 40, we end up 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.

In conclusion, the division gives 41954.33 with a balance of 0.004.
