We're dividing 804222 by 3 
We're looking to find how many times 3 goes into 804222.

On to step 1:
3 goes into 8 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 6 from 8 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Let's proceed to step 2:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 18 away from 20, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Step 3:
3 goes into 24 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 268.0
If we subtract 24 from 24, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

Let's proceed to step 4:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 2680.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

On to step 5:
3 goes into 22 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 26807.0
Deduct 21 from 22 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

Step 6:
The number 3 fits into 12 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 268074.0
Subtracting 12 from 12 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.

Let's proceed to step 7:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 268074.0
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.

Moving on to step 8:
0 divided by 3 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 268074.0
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 268074.0, with a leftover of 0.0.
