263339 divided by 2 
Let's see how many times 2 fits into 263339.

Step 1:
If we divide 2 by 2, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Moving on to step 2:
6 divided by 2 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 6 from 6 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Going ahead to step 3:
2 can be fit into 3 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtract 2 from 3 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Moving on to step 4:
When dividing 13 by 2, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1316.0
Deduct 12 from 13 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Moving on to step 5:
If we divide 13 by 2, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 13166.0
Subtract 12 from 13 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

On to step 6:
When dividing 19 by 2, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 131669.0
Subtract 18 from 19 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 131669.5
The remainder is 0 after subtracting 10 from 10.
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.
Put 0 as the next digit of the answer. 
Result so far: 131669.5
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.

Moving on to step 9:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 131669.5
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 131669.5, and the remainder is 0.0.
