We're dividing 673316 by 3 
The aim is to understand the frequency of 3 in 673316.

Going ahead to step 1:
3 goes into 6 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

Let's proceed to step 2:
If we divide 7 by 3, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 6 from 7, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Step 3:
13 divided by 3 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 224.0
Subtracting 12 from 13 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 3

Advancing to step 4:
The number 3 fits into 13 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 2244.0
If we take 12 away from 13, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

On to step 5:
The number 3 fits into 11 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 22443.0
If we take 9 away from 11, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

On to step 6:
26 divided by 3 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 224438.0
Subtract 24 from 26 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.

Let's proceed to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 224438.6
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.

Advancing to step 8:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 224438.66
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.

The final outcome is 224438.66, with a leftover of 0.002.
