Let's divide 664782 by 20
Our goal is to divide 664782 by 20.

Advancing to step 1:
20 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 20

Step 2:
If we divide 66 by 20, we get 3 and 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.
Write down 3 as next digit of the result. 
Result so far: 33.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 20

Moving on to step 4:
20 can be fit into 47 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 332.0
Subtracting 40 from 47 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 20

On to step 5:
78 divided by 20 is 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3323.0
The remainder is 18 after subtracting 60 from 78.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 20

On to step 6:
182 divided by 20 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 33239.0
If we subtract 180 from 182, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 33239.1
Deduct 20 from 20 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.

Moving on to step 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33239.1
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33239.1
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.

After the division, we end up with 33239.1 and a remainder of 0.0.
