800154 ÷ 2 
We want to figure out the number of times 800154 can be divided by 2.

Let's proceed to step 1:
If we divide 8 by 2, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Moving on to step 2:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 2

Step 3:
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: 400.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

On to step 4:
When dividing 1 by 2, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 4000.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Let's proceed to step 5:
2 goes into 15 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 40007.0
Subtract 14 from 15 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 2

On to step 6:
14 divided by 2 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 400077.0
Deduct 14 from 14 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.

Step 7:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 400077.0
Subtracting 0 from 0 leaves us 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:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 400077.0
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.

The final result is 400077.0 with a remainder of 0.0.
