649600 divided by 20 
Let's see how many times 20 fits into 649600.

Moving on to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 20

Advancing to step 2:
The number 20 fits into 64 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we take 60 away from 64, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 20

Going ahead to step 3:
49 divided by 20 is 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 40 from 49 to get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 20

Advancing to step 4:
20 goes into 96 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
The remainder is 16 after subtracting 80 from 96.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 20

On to step 5:
20 can be fit into 160 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 3248.0
The remainder is 0 after subtracting 160 from 160.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 20

Going ahead to step 6:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 32480.0
The remainder is 0 after subtracting 0 from 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 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32480.0
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.

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: 32480.0
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.

The final result is 32480.0 with a remainder of 0.0.
