Here is a plain English "FizzBuZZ" idiom (AKA pseudo code).
Not coincidentally, it's also written in the idiom programming language
which compiles to machine code as a Win32 PE.
In fact, this entire post (including this and the following commentaries)
will compile as is.
[

to fizz buzz up to a number is:
loop
break when a counter is past the number;
set a flag;
if the counter is divisible by 3 then
display "Fizz"; clear the flag;
and then;
if the counter is divisible by 5 then
display "Buzz"; clear the flag;
and then;
if the flag is set ? display the counter;
display "\n";
repeat;

] the-idiom has reached the end of the line, where all good things must end.
There is no "end" in idiom, for idiom is an end in itself.

The counter is always divisible by 3. It is not always *evenly*
divisible by 3. Maybe you want to make that more obvious.

Thanks Bruce, you're absolutely right.
[ to decide if a number is evenly divisible by another number is:
divide the number by the other number returning a quotient number and
a remainder number;
return true if the remainder is null;
] Of course, in plain English idiom, the opposite (in this case) return
false default statement should be obvious (as it is to the-idiom) and
need not be written.

In mathematics standard terminology uses "a is divisible by b"
to mean "a is an integer multiple of b". The "evenly" is not
needed.

Thanks Tim, that's an excellent point.
And while some think that redundancy in grammar is bad, it definitely
has it's uses. Since plain English idiom is more grammar than math,
the-idiom can be very forgiving.

I feel obliged to point out that the word here is "its", not "it's".
The word "it's" is a contraction for "it is". "It" is a personal
pronoun, and the possessive forms of personal pronouns are always
spelled without apostrophes, as for example "he" and "his". The
word "it" follows this rule.

If you feel a need to add some redundancy, I suggest

if the counter is divisible by 3 (meant in the mathematical
sense of being an integer multiple of 3)

In answer to your other question, thank you for asking. My
preference is not to be attributed in your website pages.
The more impersonal form "It was pointed out that ..." conveys
the most important information, and focuses readers' attention
on that information without distracting them with extraneous
information about who did the pointing.

Not if you require the result to be in the integers.

If the OP had said “integer” rather than “number”, that would have helped.
