We look at the division of 780549 by 2 
We're looking to find how many times 2 goes into 780549.

Advancing to step 1:
When dividing 7 by 2, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 6 from 7 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Going ahead to step 2:
18 divided by 2 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 18 from 18, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 2

Going ahead to step 3:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 390.0
Subtract 0 from 0 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Let's proceed to step 4:
2 goes into 5 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 3902.0
Subtract 4 from 5 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 2

Moving on to step 5:
The number 2 fits into 14 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 39027.0
Subtracting 14 from 14 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Going ahead to step 6:
2 can be fit into 9 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 390274.0
If we take 8 away from 9, we end up 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.

Moving on to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 390274.5
If we take 10 away from 10, we end up 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.

On to step 8:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 390274.5
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 390274.5
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.

The final result is 390274.5 with a remainder of 0.0.
