We're dividing 204039 by 4 
Let's see how many times 4 fits into 204039.

Going ahead to step 1:
4 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 4

Let's proceed to step 2:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 20 away from 20, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 4

Step 3:
The number 4 fits into 4 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 4

On to step 4:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 510.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 4

Moving on to step 5:
The number 4 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 5100.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Advancing to step 6:
When dividing 39 by 4, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 51009.0
If we take 36 away from 39, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 4 fits into 30 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 51009.7
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
20 divided by 4 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 51009.75
Subtracting 20 from 20 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.

Advancing to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 51009.75
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.

On to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 51009.75
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.

The final outcome is 51009.75, with a leftover of 0.0.
