Let's divide 646826 by 20
We're looking to find how many times 20 goes into 646826.

Step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 20

Going ahead to step 2:
20 can be fit into 64 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 60 from 64 leaves us with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 20

Going ahead to step 3:
46 divided by 20 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtracting 40 from 46 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 20

On to step 4:
20 can be fit into 68 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 323.0
Deduct 60 from 68 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 20

Step 5:
If we divide 82 by 20, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3234.0
If we subtract 80 from 82, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 20

Step 6:
20 can be fit into 26 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 32341.0
Subtract 20 from 26 to 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.

Advancing to step 7:
20 goes into 60 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 32341.3
Deduct 60 from 60 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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32341.3
Subtracting 0 from 0 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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 32341.3
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.

The quotient of the division is 32341.3, and the remainder is 0.0.
