204363 divided by 12 
We want to figure out the number of times 204363 can be divided by 12.

On to step 1:
2 divided by 12 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 12

Step 2:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 12 away from 20, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 12

Step 3:
12 can be fit into 84 7 times, resulting in a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 84 away from 84, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 12

Step 4:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 170.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 12

On to step 5:
36 divided by 12 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 1703.0
The remainder is 0 after subtracting 36 from 36.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 12

Step 6:
12 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 17030.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 12, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 17030.2
Deduct 24 from 30 and we're left 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.

Let's proceed to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17030.25
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17030.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17030.25
Deduct 0 from 0 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.

The final result is 17030.25 with a remainder of 0.0.
