793771 divided by 3 
The aim is to understand the frequency of 3 in 793771.

Step 1:
3 goes into 7 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

On to step 2:
If we divide 19 by 3, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 1 after subtracting 18 from 19.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Moving on to step 3:
3 can be fit into 13 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 264.0
The remainder is 1 after subtracting 12 from 13.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

On to step 4:
If we divide 17 by 3, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 2645.0
Subtract 15 from 17 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 3

Advancing to step 5:
When dividing 27 by 3, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 26459.0
Subtracting 27 from 27 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Step 6:
If we divide 1 by 3, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 264590.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 264590.3
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 264590.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 264590.33 with a remainder of 0.001.
