Let's divide 804773 by 3
The aim is to understand the frequency of 3 in 804773.

Let's proceed 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
If we take 6 away from 8, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Step 2:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 18 away from 20, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Let's proceed to step 3:
24 divided by 3 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 268.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Going ahead to step 4:
7 divided by 3 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2682.0
Subtracting 6 from 7 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Going ahead to step 5:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 26825.0
Subtracting 15 from 17 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Let's proceed to step 6:
If we divide 23 by 3, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 268257.0
The remainder is 2 after subtracting 21 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed 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: 268257.6
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.

On to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 268257.66
Subtract 18 from 20 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.

The final result is 268257.66 with a remainder of 0.002.
