We divide 631974 by 20
We're looking to find how many times 20 goes into 631974.

Moving on to step 1:
20 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 20

On to step 2:
When dividing 63 by 20, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 60 from 63 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

Step 3:
20 can be fit into 31 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 20 from 31 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 20

Going ahead to step 4:
20 can be fit into 119 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 315.0
Deduct 100 from 119 and we're left with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 20

Going ahead to step 5:
20 goes into 197 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 3159.0
If we take 180 away from 197, we end up with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 20

On to step 6:
The number 20 fits into 174 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 31598.0
The remainder is 14 after subtracting 160 from 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 20, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 31598.7
If we take 140 away from 140, 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 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31598.7
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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31598.7
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.

After the division, we end up with 31598.7 and a remainder of 0.0.
