Formatting and responding to what I think is your query:

Regex        Result
(.*)(\d*)    'I have 2 numbers: 53147', ''
(.*)(\d+)    'I have 2 numbers: 5314', '7'
(.*?)(\d*)    '', ''
(.*?)(\d+)    'I have ', '2'
(.*)(\d+)$    'I have 2 numbers: 5314', '7'

Produced by this program:

use strict;
my @re= qw|
    (.*)(\\d*)    
    (.*)(\\d+)    
    (.*?)(\\d*)   
    (.*?)(\\d+)   
    (.*)(\\d+)$   
|;

my $test ="I have 2 numbers: 53147";
print "Regex\t\tResult\n";
for (@re){
  my $r=qr|$_|;
  print "$_\t'", join( "', '",$test=~/$r/),"'\n";
}

Now - could you point out which line(s) you have trouble with ?

Also, I suggest you review:

• How do I compose an effective node title?
• How do I post a question effectively?
• Markup in the Monastery

Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Read Where should I post X? if you're not absolutely sure you're posting in the right place.

Please read these before you post! —

You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
