We divide 455369 by 3
The aim is to understand the frequency of 3 in 455369.

On to step 1:
If we divide 4 by 3, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Let's proceed to step 2:
3 goes into 15 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 15 from 15 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

On to step 3:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 151.0
Subtract 3 from 5 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

On to step 4:
If we divide 23 by 3, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 1517.0
Subtract 21 from 23 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Going ahead to step 5:
3 goes into 26 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 15178.0
The remainder is 2 after subtracting 24 from 26.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Going ahead to step 6:
If we divide 29 by 3, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 151789.0
Deduct 27 from 29 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.

On to step 7:
20 divided by 3 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 151789.6
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.

On to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 151789.66
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.

In conclusion, the division gives 151789.66 with a balance of 0.002.
