806422 ÷ 2 
We want to figure out the number of times 806422 can be divided by 2.

On to step 1:
2 goes into 8 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Step 3:
6 divided by 2 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
If we subtract 6 from 6, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Let's proceed to step 4:
When dividing 4 by 2, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 4032.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Going ahead to step 5:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 40321.0
If we subtract 2 from 2, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Let's proceed to step 6:
When dividing 2 by 2, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 403211.0
Subtract 2 from 2 to 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.

Moving on to step 7:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 403211.0
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: 403211.0
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.

The final outcome is 403211.0, with a leftover of 0.0.
