Let's divide 663164 by 20
Let's see how many times 20 fits into 663164.

Let's proceed to step 1:
20 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 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 subtract 60 from 66, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 20

Going ahead to step 3:
20 goes into 63 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 3 after subtracting 60 from 63.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 20

Let's proceed to step 4:
20 goes into 31 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 331.0
Subtract 20 from 31 to get 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 20

Going ahead to step 5:
20 can be fit into 116 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 3315.0
Deduct 100 from 116 and we're left with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 20

Let's proceed to step 6:
The number 20 fits into 164 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 33158.0
Subtract 160 from 164 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.

Step 7:
40 divided by 20 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 33158.2
If we subtract 40 from 40, 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.

Step 8:
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: 33158.2
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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 33158.2
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 33158.2 with a remainder of 0.0.
