631328 ÷ 20 
Let's see how many times 20 fits into 631328.

Step 1:
When dividing 6 by 20, we get 0 with 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.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Moving on to step 2:
20 goes into 63 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 60 from 63 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

Step 3:
31 divided by 20 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 20 from 31 to get 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 20

On to step 4:
If we divide 113 by 20, we get 5 and a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 315.0
Deduct 100 from 113 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 20

Let's proceed to step 5:
20 can be fit into 132 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 3156.0
If we take 120 away from 132, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 20

Going ahead to step 6:
20 goes into 128 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 31566.0
If we subtract 120 from 128, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
20 goes into 80 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 31566.4
The remainder is 0 after subtracting 80 from 80.
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 8:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31566.4
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.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31566.4
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 31566.4 with a remaining 0.0.
