664814 divided by 20 
Let's see how many times 20 fits into 664814.

Going ahead to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 20

Moving on to step 2:
66 divided by 20 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 60 away from 66, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 20

Step 3:
20 can be fit into 64 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 60 away from 64, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 20

Going ahead to step 4:
When dividing 48 by 20, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 332.0
If we subtract 40 from 48, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 20

Going ahead to step 5:
If we divide 81 by 20, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 3324.0
Subtracting 80 from 81 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 20

Let's proceed to step 6:
If we divide 14 by 20, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 33240.0
Subtract 0 from 14 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 20, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 33240.7
Subtracting 140 from 140 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.

Going ahead to step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33240.7
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.

Let's proceed to step 9:
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: 33240.7
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.

The final result is 33240.7 with a remainder of 0.0.
