Let's divide 266774 by 3
The aim is to understand the frequency of 3 in 266774.

Let's proceed to step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Let's proceed to step 2:
3 can be fit into 26 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 24 from 26 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Moving on to step 3:
26 divided by 3 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 88.0
The remainder is 2 after subtracting 24 from 26.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Advancing to step 4:
When dividing 27 by 3, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 889.0
Deduct 27 from 27 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Advancing to step 5:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 8892.0
Subtracting 6 from 7 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Going ahead to step 6:
3 goes into 14 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 88924.0
The remainder is 2 after subtracting 12 from 14.
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:
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: 88924.6
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.

Advancing to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 88924.66
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.

After the division, we end up with 88924.66 and a remainder of 0.002.
