We're dividing 631423 by 2 
We want to divide 631423 by 2.

Going ahead to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

Going ahead to step 2:
2 goes into 3 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 2 from 3, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

On to step 3:
If we divide 11 by 2, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 315.0
Deduct 10 from 11 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 2

Moving on to step 4:
2 goes into 14 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 3157.0
If we subtract 14 from 14, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

On to step 5:
2 divided by 2 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 31571.0
The remainder is 0 after subtracting 2 from 2.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Let's proceed to step 6:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 315711.0
The remainder is 1 after subtracting 2 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 315711.5
Subtract 10 from 10 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:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 315711.5
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.

Going ahead to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 315711.5
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 315711.5, and the remainder is 0.0.
