278715 divided by 2 
We're looking to find how many times 2 goes into 278715.

Step 1:
When dividing 2 by 2, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 2 from 2 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

Going ahead to step 2:
The number 2 fits into 7 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 6 from 7, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

On to step 3:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 139.0
Subtracting 18 from 18 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Going ahead to step 4:
If we divide 7 by 2, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1393.0
If we subtract 6 from 7, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Moving on to step 5:
11 divided by 2 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 13935.0
If we take 10 away from 11, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Going ahead to step 6:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 139357.0
If we take 14 away from 15, 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.

On to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 139357.5
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.

Advancing 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: 139357.5
The remainder is 0 after subtracting 0 from 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 9:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 139357.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 139357.5 with a remaining 0.0.
