Anyone know how to stop a div from moving to the next line?

I want the following:

"One, Two, Three"


But all I can get is:

"One,
Two,
Three"

here is the code I have been using.

<p>One,<DIV style="width: 286; height: 57">Two,</DIV> Three</p>

Anyone know how to keep the div, but make this all appear on one line?
