459465 ÷ 3 
The aim is to understand the frequency of 3 in 459465.

Step 1:
When dividing 4 by 3, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

On to step 2:
3 goes into 15 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 15 from 15 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Going ahead to step 3:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtract 9 from 9 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

Moving on to step 4:
4 divided by 3 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1531.0
Subtract 3 from 4 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Advancing to step 5:
16 divided by 3 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 15315.0
The remainder is 1 after subtracting 15 from 16.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Advancing to step 6:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 153155.0
The remainder is 0 after subtracting 15 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 153155.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 153155.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 153155.0 with a remaining 0.0.
