-@defun / dividend divisor &rest divisors
-This function divides @var{dividend} by @var{divisor} and returns the
-quotient. If there are additional arguments @var{divisors}, then it
-divides @var{dividend} by each divisor in turn. Each argument may be a
-number or a marker.
+@defun / dividend &rest divisors
+The @code{/} function serves two purposes: inversion and division. When
+@code{/} has a single argument, the value is the inverse of the
+argument. When there are multiple arguments, @code{/} divides
+@var{dividend} by each of the @var{divisors}, cumulatively, returning
+the quotient. If there are no arguments, an error is signaled.
