688678 divided by 2 
We want to figure out the number of times 688678 can be divided by 2.

Let's proceed to step 1:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 6 from 6 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

On to step 2:
If we divide 8 by 2, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

On to step 3:
If we divide 8 by 2, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 344.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Moving on to step 4:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3443.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 2

Going ahead to step 5:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 34433.0
Subtracting 6 from 7 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

On to step 6:
When dividing 18 by 2, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 344339.0
If we subtract 18 from 18, 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 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 344339.0
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.

Let's proceed to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 344339.0
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.

In conclusion, the division gives 344339.0 with a balance of 0.0.
