Let's divide 508602 by 12
We want to figure out the number of times 508602 can be divided by 12.

Going ahead to step 1:
The number 12 fits into 5 0 times, leaving 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.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 12

Going ahead to step 2:
50 divided by 12 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 48 from 50 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 12

Moving on to step 3:
12 can be fit into 28 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 24 from 28 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 12

On to step 4:
12 goes into 46 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 423.0
Subtract 36 from 46 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 12

Moving on to step 5:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 4238.0
If we subtract 96 from 100, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 12

Moving on to step 6:
The number 12 fits into 42 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 42383.0
If we take 36 away from 42, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
12 goes into 60 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 42383.5
Deduct 60 from 60 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42383.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42383.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 42383.5, with a leftover of 0.0.
