-@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
+@defun / number &rest divisors
+With one or more @var{divisors}, this function divides @var{number}
+by each divisor in @var{divisors} in turn, and returns the quotient.
+With no @var{divisors}, this function returns 1/@var{number}, i.e.,
+the multiplicative inverse of @var{number}. Each argument may be a
