Dividing two Count() Results

Just a quick question, how do I divide the results of these two queries
together ?

(select count (*) as ontime from schedule where actualarrivaldate <=
estimatearrivaldate)

(select count (*) as total from schedule)

Thanks for any help
RobertSELECT ontime, total, ontime/CAST(total AS REAL)
FROM
(SELECT COUNT(CASE WHEN actualarrivaldate <= estimatearrivaldate
THEN 1 END), COUNT(*)
FROM schedule) AS X(ontime,total)
