Let's divide 820445 by 3
We're looking to find how many times 3 goes into 820445.

On to step 1:
3 goes into 8 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

Let's proceed 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
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:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 273.0
If we subtract 9 from 10, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

On to step 4:
14 divided by 3 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 2734.0
If we take 12 away from 14, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Advancing to step 5:
24 divided by 3 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 27348.0
The remainder is 0 after subtracting 24 from 24.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Advancing to step 6:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 273481.0
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.

On to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 273481.6
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:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 273481.66
If we subtract 18 from 20, we 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.

The final result is 273481.66 with a remainder of 0.002.
