501902 ÷ 12 
We want to figure out the number of times 501902 can be divided by 12.

Moving on to step 1:
12 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

Moving on to step 2:
50 divided by 12 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 48 from 50, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 12

Moving on to step 3:
The number 12 fits into 21 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 12 from 21 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 12

Moving on to step 4:
If we divide 99 by 12, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 418.0
If we subtract 96 from 99, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 12

On to step 5:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 4182.0
If we subtract 24 from 30, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 12

Moving on to step 6:
12 can be fit into 62 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 41825.0
The remainder is 2 after subtracting 60 from 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 41825.1
The remainder is 8 after subtracting 12 from 20.
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 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 41825.16
If we subtract 72 from 80, we 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.

Let's proceed to step 9:
80 divided by 12 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 41825.166
The remainder is 8 after subtracting 72 from 80.
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 41825.166 with a balance of 0.0008.
