Q:

How to get single digit in a integer in Scheme

hi I am a scheme beginner, have an assignment that need to determine leapy year.  But i noticed there is no use of (/ 1992 100) to get 19 like C. And there is also no % operator to get a reminder.thanks. 

A:

guile> (quotient 1992 100)
19
guile> (modulo 1992 100)
92
