    Perl:

    sub repeatedString {
    my ($s, $n) = @_;

    my $a = scalar(grep { $_ eq "a" } split("", $s));
    my $remainder = scalar(grep { $_ eq "a" } split("", substr($s, 0, ($n % length($s)))));
    return ($n % length($s) == 0) ? $a * ($n / length($s)) : $a * int($n / length($s)) + $remainder;
}
