I need to extract some data from a cell please let me know any suggestion you
may have for a formula.

Right now in a cell I have the number 50323113211. In a database I have...I
know that the number that needs to be extracted from this particular number
is 503. What formula can I use to extract this so that the 23113211 remains?
I have a list of 50,000 entries and the number varies. So in another cell i
may have 1342234 and in the next cell I am told I need to pull the 1 so that
the 343324 remains.

Now once the first part of this is done... I need from database range to
pull out the number it finds. So for example, let's say for the example of
23113211, there is a range in cells that has for example 23, 24, 25, 26. I
then need this range to be checked with the 23113211 and then pull out the
match. So in this case it finds that 23 is the match and then pulls it out
and leaves me with 113211. I know this is omplicated and confusing. Any
thoughts? Thanks.
