finding string in very long file without newlines

What's the best way to find a string in a very long file without newlines in Unix? The standard utility I'm aware of for finding a string in a single file is grep, but for a long file without newlines, I think the output is just going to be the input. I suppose I could use sed to replace the string with another that catches my eye like "AAAAAAAAAAAAAAAAAAAAAAAAAAAAA," and search for it visually, but with an extremely large file that would be impractical.

nl(3XCURSES)						  X/Open Curses Library Functions					      nl(3XCURSES)

NAME
nl, nonl - enable/disable newline control SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib -R /usr/xpg4/lib -lcurses [ library... ] c89 [ flag... ] file... -lcurses [ library... ] #include <curses.h> int nl(void); int nonl(void); DESCRIPTION
The nl() function enables the handling of newlines. The nl() function converts newline into carriage return and line feed on output and converts carriage return into newline on input. nonl() disables the handling of newlines. The handling of newlines is initially enabled. Disabling the handling of newlines results in faster cursor motion since X/Open Curses can use the line-feed capability more efficiently. RETURN VALUES
On success, these functions return OK. Otherwise, they return ERR. ERRORS
None. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ |MT-Level |Unsafe | +-----------------------------+-----------------------------+ SEE ALSO
