I don't know about other architectures, but on Intel processors, this will
also depend on the *sequence* of inputs. Each core has only one divider and
the divider cannot accept new operations at fixed interval, let alone every
cycle. Certain on-going divisions prevent it from accepting new input until
later in the operation.
