We look at the division of 455576 by 3 
The aim is to understand the frequency of 3 in 455576.

Moving on to step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Going ahead to step 2:
If we divide 15 by 3, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 15 from 15 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Step 3:
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: 151.0
Deduct 3 from 5 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Moving on to step 4:
25 divided by 3 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1518.0
If we take 24 away from 25, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

On to step 5:
If we divide 17 by 3, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 15185.0
Subtracting 15 from 17 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Step 6:
If we divide 26 by 3, we get 8 and a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 151858.0
If we subtract 24 from 26, 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.

Moving on to step 7:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 151858.6
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.

Going ahead to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 151858.66
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.

The final outcome is 151858.66, with a leftover of 0.002.
