The simplest, but not necessarily the most elegant way is to explode the string on " " and then loop through the array building up the string again, when your counter gets to 50 you add the short code. This also allows you to choose to do it after 40 if the total length is <80, for example. One thing to test for is if the string ends in </p> or /div then you would want to insert it in the middle of the string. Have a play and test a few different content strings and tweak it to how you need it
