(defun percent (n d)
  (let ((pct (* 100 (/ n d 1.0))))
    (message "%.1f%%" pct)))

(percent 13973 204612) ; 6.8%

One thing I don't understand tho - from the `format' docstring

  For %e and %f sequences, the number after the "." in the
  precision specifier says how many decimal places to show; if
  zero, the decimal point itself is omitted.

Still (percent 0 200) ; 0.0%

Or does that refer to "if one _sets_ it to zero"

(message "%.0f%%" 0) ; 0%

Right, so that's it... Yeah, so obvious, saying it makes one
confused instead :)
