815395 ÷ 3 
We want to figure out the number of times 815395 can be divided by 3.

Moving on to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Moving on to step 2:
When dividing 21 by 3, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 21 from 21 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Step 3:
When dividing 5 by 3, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 271.0
Deduct 3 from 5 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Going ahead to step 4:
3 goes into 23 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 2717.0
Subtract 21 from 23 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Moving on to step 5:
When dividing 29 by 3, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 27179.0
If we subtract 27 from 29, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

On to step 6:
If we divide 25 by 3, we get 8 and a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 271798.0
Deduct 24 from 25 and we're left 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.

Going ahead to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 271798.3
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.

Moving on to step 8:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 271798.33
Deduct 9 from 10 and we're left 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 271798.33, and the remainder is 0.001.
