We look at the division of 823073 by 3 
Let's see how many times 3 fits into 823073.

Moving on 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
Subtracting 6 from 8 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

On to step 2:
If we divide 22 by 3, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 21 from 22 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Step 3:
3 goes into 13 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 274.0
The remainder is 1 after subtracting 12 from 13.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Moving on to step 4:
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: 2743.0
Subtracting 9 from 10 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

On to step 5:
3 goes into 17 5 times with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 27435.0
The remainder is 2 after subtracting 15 from 17.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Moving on to step 6:
3 goes into 23 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 274357.0
If we take 21 away from 23, 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.

On to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 274357.6
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.

Step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 274357.66
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 final result is 274357.66 with a remainder of 0.002.
