In the spirit of @edi's answer, but with some explanation of what's happening. Match the beginning of the line with ^, then look for a sequence of characters that are not whitespace with [^\s]* or \S* (the former may work in more editors, libraries, etc than the latter), then find the first whitespace character with \s. Putting these together, you have

^[^\s]*\s

You may want to group the non-whitespace and whitespace parts, so you can do the replacement you're talking about:

^([^\s]*)(\s)

Then the replacement pattern is just \1/
