We look at the division of 814864 by 20 
Let's see how many times 20 fits into 814864.

Step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 20

Advancing to step 2:
If we divide 81 by 20, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 80 from 81, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 20

Step 3:
When dividing 14 by 20, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 20

Step 4:
20 goes into 148 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 407.0
Subtract 140 from 148 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 20

On to step 5:
When dividing 86 by 20, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4074.0
Subtract 80 from 86 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 20

Going ahead to step 6:
The number 20 fits into 64 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 40743.0
If we take 60 away from 64, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 40743.2
Subtract 40 from 40 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.

Moving on to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40743.2
Deduct 0 from 0 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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40743.2
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.

In conclusion, the division gives 40743.2 with a balance of 0.0.
