816460 ÷ 3 
We want to figure out the number of times 816460 can be divided by 3.

Advancing to step 1:
When dividing 8 by 3, we get 2 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 (1) from the dividend, attach it to 2 and continue: 21 / 3

Moving on to step 2:
21 divided by 3 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtracting 21 from 21 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Let's proceed to step 3:
3 can be fit into 6 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 272.0
Subtracting 6 from 6 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 3

Advancing to step 4:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 2721.0
Subtracting 3 from 4 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

On to step 5:
If we divide 16 by 3, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 27215.0
If we subtract 15 from 16, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Going ahead to step 6:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 272153.0
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 272153.3
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 272153.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 272153.33, and the remainder is 0.001.
