313257 divided by 2 
We want to divide 313257 by 2.

Going ahead to step 1:
3 divided by 2 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Advancing to step 2:
2 goes into 11 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 1 after subtracting 10 from 11.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

On to step 3:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we subtract 12 from 13, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

On to step 4:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1566.0
Deduct 12 from 12 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Moving on to step 5:
When dividing 5 by 2, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 15662.0
The remainder is 1 after subtracting 4 from 5.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 2

On to step 6:
When dividing 17 by 2, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 156628.0
Deduct 16 from 17 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 156628.5
Deduct 10 from 10 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:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 156628.5
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.

Moving on to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 156628.5
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.

After the division, we end up with 156628.5 and a remainder of 0.0.
