We look at the division of 646806 by 20 
We're looking to find how many times 20 goes into 646806.

On to step 1:
20 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 20

Going ahead to step 2:
20 can be fit into 64 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 64, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 20

Step 3:
20 goes into 46 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 6 after subtracting 40 from 46.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 20

Step 4:
20 can be fit into 68 3 times, resulting in a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 323.0
Deduct 60 from 68 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 20

Moving on to step 5:
20 goes into 80 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 3234.0
Subtracting 80 from 80 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 20

Step 6:
6 divided by 20 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 32340.0
If we subtract 0 from 6, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
20 goes into 60 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 32340.3
The remainder is 0 after subtracting 60 from 60.
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 next digit of our result is 0. 
Result so far: 32340.3
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.

Advancing to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32340.3
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.

In conclusion, the division gives 32340.3 with a balance of 0.0.
