We divide 631810 by 20
Let's see how many times 20 fits into 631810.

On 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
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 20

Let's proceed to step 2:
20 can be fit into 63 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 60 from 63 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

Moving on to step 3:
The number 20 fits into 31 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 20 from 31 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 20

Going ahead to step 4:
When dividing 118 by 20, we get 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Subtracting 100 from 118 leaves us with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 20

Advancing to step 5:
When dividing 181 by 20, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 3159.0
Deduct 180 from 181 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 20

Let's proceed to step 6:
20 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 31590.0
Subtracting 0 from 10 leaves us 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.

Moving on to step 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 31590.5
Subtracting 100 from 100 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.

On to step 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31590.5
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.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31590.5
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.

The quotient of the division is 31590.5, and the remainder is 0.0.
