Let's divide 844173 by 20
Let's see how many times 20 fits into 844173.

Advancing to step 1:
20 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 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.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 80 from 84, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 20

Going ahead to step 3:
20 goes into 44 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 40 from 44, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 20

Going ahead to step 4:
The number 20 fits into 41 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 422.0
The remainder is 1 after subtracting 40 from 41.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 20

Let's proceed to step 5:
The number 20 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 4220.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 20

On to step 6:
20 can be fit into 173 8 times, resulting in a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 42208.0
Deduct 160 from 173 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
130 divided by 20 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 42208.6
Deduct 120 from 130 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 42208.65
Subtract 100 from 100 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.

Step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42208.65
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.

Moving on to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42208.65
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.

Our division results in 42208.65 with a remaining 0.0.
