We look at the division of 3664 by 20 
Let's see how many times 20 fits into 3664.

Moving on to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 20

Let's proceed to step 2:
20 can be fit into 36 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 20 from 36 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 20

Let's proceed to step 3:
20 goes into 166 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 160 from 166 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 20

Step 4:
If we divide 64 by 20, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 183.0
Subtract 60 from 64 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 5:
The number 20 fits into 40 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 183.2
Subtract 40 from 40 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.

On to step 6:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 183.2
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.

Advancing to step 7:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 183.2
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.

Our division results in 183.2 with a remaining 0.0.
