639048 divided by 20 
We want to divide 639048 by 20.

Going ahead to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 20

Going ahead to step 2:
20 can be fit into 63 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 60 from 63 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 20

Going ahead to step 3:
The number 20 fits into 39 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 20 away from 39, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 20

Going ahead to step 4:
When dividing 190 by 20, we get 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 319.0
The remainder is 10 after subtracting 180 from 190.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 20

Going ahead to step 5:
20 can be fit into 104 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 3195.0
Subtract 100 from 104 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

Moving on to step 6:
If we divide 48 by 20, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 31952.0
The remainder is 8 after subtracting 40 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
If we divide 80 by 20, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 31952.4
Subtracting 80 from 80 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.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 31952.4
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 31952.4
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 31952.4 with a remaining 0.0.
