We're dividing 1277264 by 2 
We want to divide 1277264 by 2.

On to step 1:
When dividing 1 by 2, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

On to step 2:
2 goes into 12 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 12 from 12 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

Let's proceed to step 3:
When dividing 7 by 2, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtracting 6 from 7 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Advancing to step 4:
The number 2 fits into 17 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 638.0
If we subtract 16 from 17, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Going ahead to step 5:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6386.0
If we subtract 12 from 12, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Going ahead to step 6:
2 goes into 6 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 63863.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Going ahead to step 7:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 638632.0
Subtracting 4 from 4 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.

Moving on to step 8:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 638632.0
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.

Step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 638632.0
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.

The final outcome is 638632.0, with a leftover of 0.0.
