Let's divide 602515 by 12
We want to divide 602515 by 12.

Step 1:
6 divided by 12 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 12

Step 2:
When dividing 60 by 12, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 60 away from 60, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 12

Moving on to step 3:
The number 12 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 12

Going ahead to step 4:
25 divided by 12 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 502.0
If we take 24 away from 25, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 12

Going ahead to step 5:
11 divided by 12 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 5020.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 12

Step 6:
12 goes into 115 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 50209.0
If we take 108 away from 115, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
12 goes into 70 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 50209.5
Subtracting 60 from 70 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 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 50209.58
The remainder is 4 after subtracting 96 from 100.
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 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 50209.583
Deduct 36 from 40 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.

On to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 50209.5833
Subtracting 36 from 40 leaves us 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.

The final result is 50209.5833 with a remainder of 4e-05.
