We divide 844656 by 20
We want to figure out the number of times 844656 can be divided by 20.

Going ahead to step 1:
8 divided by 20 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 20

Moving on to 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
Subtracting 80 from 84 leaves us with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 20

Let's proceed to step 3:
If we divide 44 by 20, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 40 from 44 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 20

Moving on to step 4:
20 goes into 46 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 422.0
If we subtract 40 from 46, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 20

Advancing to step 5:
20 can be fit into 65 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 4223.0
Subtract 60 from 65 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 20

Step 6:
The number 20 fits into 56 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 42232.0
The remainder is 16 after subtracting 40 from 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
20 can be fit into 160 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 42232.8
Subtracting 160 from 160 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.

Step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42232.8
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.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42232.8
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.

The final outcome is 42232.8, with a leftover of 0.0.
