Scroll down to the end of the div

Question

I have the code

1 - $("#fluxo-msg").load('fluxo-mensagem.php', {fake:fake, user:user});
2 -
3 - $('html, body').animate({
4 -    scrollTop: $("#vemaqui").offset().top
5 - }, 1000);

In the line 1 i upload a file that contains the content the user will view

In the line 3,4,5 me trying make sure that after you load the page, it goes down to the div #vemaqui. The problem is that it loads the file, but the scroll does not descend to the div #vemaqui (that is inside the content that will be loaded by the function load()). To div #msg flow that is responsible for receiving the content has a limit of height** de **300px** e como o conteúdo é grande, eu coloquei umoverflow: auto` then after passing the 300px it generates a scroll.
