We look at the division of 4102775 by 3 
The aim is to understand the frequency of 3 in 4102775.

Going ahead to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 3

On to step 2:
3 goes into 11 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 9 from 11 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Advancing to step 3:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtract 18 from 20 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Advancing to step 4:
3 goes into 22 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1367.0
The remainder is 1 after subtracting 21 from 22.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

Advancing to step 5:
When dividing 17 by 3, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 13675.0
Subtracting 15 from 17 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 3

On to step 6:
3 goes into 27 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 136759.0
The remainder is 0 after subtracting 27 from 27.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Let's proceed to step 7:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1367591.0
The remainder is 2 after subtracting 3 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1367591.6
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.

Going ahead to step 9:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1367591.66
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 1367591.66 with a remainder of 0.002.
