815312 ÷ 3 
Let's see how many times 3 fits into 815312.

Let's proceed to step 1:
8 divided by 3 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Advancing to step 2:
21 divided by 3 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 21 from 21 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Advancing to step 3:
If we divide 5 by 3, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 271.0
Subtracting 3 from 5 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Moving on to step 4:
23 divided by 3 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 2717.0
If we subtract 21 from 23, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Moving on to step 5:
21 divided by 3 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27177.0
Subtract 21 from 21 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Step 6:
When dividing 2 by 3, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 271770.0
Subtracting 0 from 2 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 271770.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 271770.66
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 271770.66, and the remainder is 0.002.
