820091 ÷ 3 
We're looking to find how many times 3 goes into 820091.

Moving on to step 1:
3 goes into 8 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 6 from 8, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

Going ahead to step 2:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 1 after subtracting 21 from 22.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Going ahead to step 3:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 273.0
If we take 9 away from 10, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Let's proceed to step 4:
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: 2733.0
The remainder is 1 after subtracting 9 from 10.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

On to step 5:
The number 3 fits into 19 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 27336.0
If we subtract 18 from 19, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

Step 6:
When dividing 11 by 3, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 273363.0
Subtract 9 from 11 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 273363.6
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.

Moving on to step 8:
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: 273363.66
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 273363.66, and the remainder is 0.002.
