844004 divided by 20 
Let's see how many times 20 fits into 844004.

Moving on to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 20

Step 2:
The number 20 fits into 84 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 80 away from 84, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 20

Let's proceed to step 3:
20 goes into 44 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 40 away from 44, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 20

Moving on to step 4:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 422.0
If we subtract 40 from 40, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 20

Moving on to step 5:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4220.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 20

Let's proceed to step 6:
The number 20 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 42200.0
The remainder is 4 after subtracting 0 from 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 7:
40 divided by 20 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 42200.2
Subtracting 40 from 40 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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42200.2
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.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42200.2
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 42200.2, with a leftover of 0.0.
