'How can I write this code less and better in Laravel?

How can I write this code less and better in Laravel? I am writing this code to remove the / r character in the input text and also to calculate the number of characters in the text.

$removeRchar = Str::remove("\r", $request['message']);
    $length = Str::length($removeRchar);
    if ($length <= 70) {
        $pages = 1;
    } else {
        $pages = ceil($length / 70);
    }
laravel
