Let's divide 846311 by 20
We're looking to find how many times 20 goes into 846311.

Advancing to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the 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

Moving on to step 2:
The number 20 fits into 84 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 4 after subtracting 80 from 84.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 20

Moving on to step 3:
20 can be fit into 46 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 40 from 46 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 20

Moving on to step 4:
The number 20 fits into 63 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 423.0
If we subtract 60 from 63, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 20

Moving on to step 5:
If we divide 31 by 20, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 4231.0
The remainder is 11 after subtracting 20 from 31.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 20

On to step 6:
If we divide 111 by 20, we get 5 and a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 42315.0
If we take 100 away from 111, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
20 goes into 110 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 42315.5
Subtracting 100 from 110 leaves us 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.

On to 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: 42315.55
Deduct 100 from 100 and we're left 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 42315.55 with a remaining 0.0.
