664546 divided by 20 
We want to figure out the number of times 664546 can be divided by 20.

Advancing to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 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.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 20

On to step 3:
20 can be fit into 64 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Let's proceed to step 4:
When dividing 45 by 20, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 332.0
Subtract 40 from 45 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 20

Let's proceed to step 5:
The number 20 fits into 54 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 3322.0
Deduct 40 from 54 and we're left with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 20

Step 6:
When dividing 146 by 20, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 33227.0
Deduct 140 from 146 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 33227.3
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:
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: 33227.3
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33227.3
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 33227.3, and the remainder is 0.0.
