We're dividing 301808 by 3 
The aim is to understand the frequency of 3 in 301808.

Moving on to step 1:
3 can be fit into 3 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

On to step 2:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Step 3:
If we divide 1 by 3, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Going ahead to step 4:
If we divide 18 by 3, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1006.0
If we take 18 away from 18, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Advancing to step 5:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10060.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 6:
When dividing 8 by 3, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 100602.0
The remainder is 2 after subtracting 6 from 8.
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 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 100602.6
Deduct 18 from 20 and we're left 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.

Step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 100602.66
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.

In conclusion, the division gives 100602.66 with a balance of 0.002.
