789918 divided by 2 
We want to figure out the number of times 789918 can be divided by 2.

On to step 1:
2 goes into 7 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 6 from 7 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

On to step 2:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Moving on to step 3:
9 divided by 2 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 394.0
Subtract 8 from 9 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Step 4:
2 goes into 19 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 3949.0
Subtracting 18 from 19 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Moving on to step 5:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 39495.0
Subtracting 10 from 11 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

Advancing to step 6:
When dividing 18 by 2, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 394959.0
If we take 18 away from 18, 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 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 394959.0
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.

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: 394959.0
Deduct 0 from 0 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.

The final outcome is 394959.0, with a leftover of 0.0.
