How to define repeated string when using the re module?

[smith jack]

if it's for a single character, this should be very easy, such as
c{m,n}   the occurrence of c is between m and n,

if i want to define the occurrence of (.*?)</div>  how should make it
done?  ((.*?)</div>){1,3}  seems not work, any method to define repeat
string using python regex?
