We look at the division of 827780 by 3 
The aim is to understand the frequency of 3 in 827780.

Let's proceed 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
The remainder is 2 after subtracting 6 from 8.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Let's proceed 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
Subtracting 21 from 22 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 3

On to step 3:
When dividing 17 by 3, we get 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 275.0
If we subtract 15 from 17, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

Advancing to step 4:
The number 3 fits into 27 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 2759.0
Deduct 27 from 27 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Let's proceed to step 5:
If we divide 8 by 3, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 27592.0
Subtract 6 from 8 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Step 6:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 275926.0
Subtracting 18 from 20 leaves us 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.
The next digit of our result is 6. 
Result so far: 275926.6
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.

Advancing 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: 275926.66
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.

The final result is 275926.66 with a remainder of 0.002.
