678568 ÷ 2 
We're looking to find how many times 2 goes into 678568.

Advancing to step 1:
If we divide 6 by 2, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Going ahead to step 2:
If we divide 7 by 2, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 1 after subtracting 6 from 7.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Going ahead to step 3:
The number 2 fits into 18 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 339.0
The remainder is 0 after subtracting 18 from 18.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

On to step 4:
2 can be fit into 5 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 3392.0
If we subtract 4 from 5, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Going ahead to step 5:
2 goes into 16 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 33928.0
Deduct 16 from 16 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Let's proceed to step 6:
If we divide 8 by 2, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 339284.0
Deduct 8 from 8 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 7:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 339284.0
If we take 0 away from 0, 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.
Put 0 as the next digit of the answer. 
Result so far: 339284.0
If we take 0 away from 0, 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.

In conclusion, the division gives 339284.0 with a balance of 0.0.
