We look at the division of 820685 by 3 
We're looking to find how many times 3 goes into 820685.

On to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 6 from 8 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Moving on to step 2:
22 divided by 3 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 21 from 22, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Advancing to step 3:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 273.0
Deduct 9 from 10 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

On to step 4:
3 goes into 16 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 2735.0
Deduct 15 from 16 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Moving on to step 5:
If we divide 18 by 3, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 27356.0
Deduct 18 from 18 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Going ahead to step 6:
3 goes into 5 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 273561.0
If we take 3 away from 5, 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.

Going ahead to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 273561.6
Deduct 18 from 20 and we're left 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.

Going ahead to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 273561.66
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.

In conclusion, the division gives 273561.66 with a balance of 0.002.
