688407 divided by 2 
We want to figure out the number of times 688407 can be divided by 2.

Let's proceed to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 2

Step 2:
When dividing 8 by 2, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 8 from 8, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Step 3:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 344.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Step 4:
2 goes into 4 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 3442.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Step 5:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 34420.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

Going ahead to step 6:
2 can be fit into 7 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 344203.0
If we take 6 away from 7, 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.

Going ahead to step 7:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 344203.5
The remainder is 0 after subtracting 10 from 10.
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.
Use 0 as the next digit of our solution. 
Result so far: 344203.5
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.

Going ahead to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 344203.5
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.

The final result is 344203.5 with a remainder of 0.0.
