We look at the division of 806415 by 3 
Our goal is to divide 806415 by 3.

Moving on to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 3

On to step 2:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtracting 18 from 20 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Moving on to step 3:
The number 3 fits into 26 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 268.0
If we take 24 away from 26, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Let's proceed to step 4:
3 can be fit into 24 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 2688.0
Deduct 24 from 24 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Moving on to step 5:
If we divide 1 by 3, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 26880.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Step 6:
When dividing 15 by 3, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 268805.0
Deduct 15 from 15 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.

Moving on to step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 268805.0
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.

On to step 8:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 268805.0
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 outcome is 268805.0, with a leftover of 0.0.
