631956 divided by 20 
Let's see how many times 20 fits into 631956.

Let's proceed to step 1:
20 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 20

Going ahead to step 2:
63 divided by 20 is 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

Moving on to step 3:
When dividing 31 by 20, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 11 after subtracting 20 from 31.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 20

Let's proceed to step 4:
20 goes into 119 5 times with 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.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 20

Advancing to step 5:
20 goes into 195 9 times with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 3159.0
If we take 180 away from 195, we end up with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 20

On to step 6:
The number 20 fits into 156 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 31597.0
If we take 140 away from 156, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 20, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 31597.8
Subtract 160 from 160 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.

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: 31597.8
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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31597.8
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 final outcome is 31597.8, with a leftover of 0.0.
