You can do like this, if the number of character is fixed
#!/usr/bin/perl
use strict;
use warnings;
my $str="30 30 36 33 36 36 36 33 36 34 26 24 21 17 17 23 27 27 31 31 3
+4 33 33 33 36 36 37 38 38 38 38 38 35 40 34 34 34 31 37 36 37 37 40 4
+0 49 40 40 40 40 40 40 40 40 33 30 30 30 30 30 42 45 45 45 45 45 49 4
+2 42";
open (OUT,">format.out");
my @array=split(/ /,$str);
for (0..19){
print OUT "$array[$_] ";
}
close(OUT);

Updated after the reply from heidi
I misunderstood the question, thanks for the reply heidi. So here is the code you needed,
#!/usr/bin/perl
use strict;
use warnings;
my $str="30 30 36 33 36 36 36 33 36 34 26 24 21 17 17 23 27 27 31 31 3
+4 33 33 33 36 36 37 38 38 38 38 38 35 40 34 34 34 31 37 36 37 37 40 4
+0 49 40 40 40 40 40 40 40 40 33 30 30 30 30 30 42 45 45 45 45 45 49 4
+2 42";
open (OUT,">format.out");
my @array=split(/ /,$str);
my $cnt=0;
foreach (0..$#array){
++$cnt;
if ($cnt % 20 == 0){
print OUT "$array[$_]\n";
}
else{
print OUT "$array[$_] ";
}
}
close(OUT);

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
