Print string while adding newlines

Question

I'm trying to print out a string with embedded ruby to a webpage, if I use the following it ends up going off of the page.

<%= comment.body %>

I want to do something like this so that it automatically prints everything with new lines

<%= comment.body[0..136] %>
<%= "\n" %>
<%= comment.body[137..250] %>

I've done the following however it prints the characters with spaces between them and ignores spaces in the string.

<% for i in 0..comment.body.length do %>
<%= i %>
<% end %>

Thanks

Solved it by using CSS

in HTML:

<p id="commentBody">
  ...
</p>

in CSS:

#commentBody {
  word-wrap: break-word;
}

Why not use HTML?

<% for i in 0..comment.body.length do %>
  <%= i %><br>
<% end %>
