We divide 631890 by 20
We want to divide 631890 by 20.

Moving on to step 1:
6 divided by 20 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 20

Let's proceed to step 2:
63 divided by 20 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 63 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 20

Going ahead to step 3:
When dividing 31 by 20, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 20 from 31, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 20

Moving on to step 4:
20 can be fit into 118 5 times, resulting in a remainder of 18.
The next digit of our result is 5. 
Result so far: 315.0
The remainder is 18 after subtracting 100 from 118.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 20

Let's proceed to step 5:
When dividing 189 by 20, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 3159.0
If we subtract 180 from 189, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 20

Step 6:
The number 20 fits into 90 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 31594.0
Deduct 80 from 90 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31594.5
Subtract 100 from 100 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.

Moving on to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31594.5
Subtract 0 from 0 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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31594.5
Subtract 0 from 0 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.

The quotient of the division is 31594.5, and the remainder is 0.0.
