We divide 664256 by 20
We want to divide 664256 by 20.

Let's proceed to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 20

Moving on to step 2:
If we divide 66 by 20, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 60 from 66 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 20

Moving on to step 3:
20 can be fit into 64 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 60 away from 64, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 20

Let's proceed to step 4:
When dividing 42 by 20, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 332.0
If we take 40 away from 42, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 20

Advancing to step 5:
20 goes into 25 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 3321.0
Subtract 20 from 25 to get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 20

Let's proceed to step 6:
If we divide 56 by 20, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 33212.0
If we subtract 40 from 56, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
20 goes into 160 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 33212.8
The remainder is 0 after subtracting 160 from 160.
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33212.8
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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33212.8
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.

The final result is 33212.8 with a remainder of 0.0.
