What do you want to fix? If pi is already there,
than a 0-step process is sufficient, the process says:

hi I am at pi

Or if you want you can use a 1-step process, one
that starts with Euler number e:

hi I am at e
now I add pi-e to myself
hi I am at pi

I guess you mean Q-series or something. Yes pi is
irrational, no element from Q. And a Q-series will
never hit pi on its way. Here is a proof:

Proof: Assume a Q-series would hit pi on its way.
Then there would be an index n, such that sn=pi,
the partial sum up to n summands would equal pi.

But each partial sum of a Q-series is from Q, and
pi is not from Q, so we would get a contradiction
saying pi is from Q, since it would be sn=pi.

So by proof by contradiction the
Q-series cannot hit pi.
