We look at the division of 804639 by 4 
Let's see how many times 4 fits into 804639.

Step 1:
When dividing 8 by 4, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Going ahead to step 2:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 0 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 4

Advancing to 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: 201.0
Subtract 4 from 4 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 4

Let's proceed to step 4:
The number 4 fits into 6 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 2011.0
The remainder is 2 after subtracting 4 from 6.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 4

Going ahead to step 5:
The number 4 fits into 23 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 20115.0
If we subtract 20 from 23, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 4

Moving on to step 6:
4 can be fit into 39 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 201159.0
If we subtract 36 from 39, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
4 goes into 30 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 201159.7
Subtract 28 from 30 to 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.

On to step 8:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 201159.75
If we subtract 20 from 20, 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.

Step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 201159.75
If we subtract 0 from 0, 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.

On to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 201159.75
Subtract 0 from 0 to 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.

In conclusion, the division gives 201159.75 with a balance of 0.0.
