We look at the division of 631868 by 2 
Let's see how many times 2 fits into 631868.

Let's proceed to step 1:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 6 away from 6, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Step 2:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 1 after subtracting 2 from 3.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Let's proceed to step 3:
2 can be fit into 11 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 315.0
If we subtract 10 from 11, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Moving on to step 4:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3159.0
Subtract 18 from 18 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Advancing to step 5:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 31593.0
Subtracting 6 from 6 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Going ahead to step 6:
If we divide 8 by 2, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 315934.0
Subtract 8 from 8 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.

Let's proceed to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 315934.0
Deduct 0 from 0 and we're left 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.

Let's proceed to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 315934.0
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 final result is 315934.0 with a remainder of 0.0.
