We look at the division of 108310 by 3 
The aim is to understand the frequency of 3 in 108310.

Let's proceed to step 1:
1 divided by 3 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Moving on to step 2:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 9 from 10.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Step 3:
18 divided by 3 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 0 after subtracting 18 from 18.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 3

Advancing to step 4:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 361.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

On to step 5:
3 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 3610.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Advancing to step 6:
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: 36103.0
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 3 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 36103.3
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 36103.33
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.

The final outcome is 36103.33, with a leftover of 0.001.
