You are asking how to use setting circles for finding something that you know the right ascension and declination for right?

http://www.bpccs.com/lcas/Articles/setcircl.htm has a brief description and the method 1 they describe is the one I used before using my dobsonian telescope. I think star hopping is far easier to use and teaches you much faster about the sky. But setting circles are useful if you want to find something and don't know about star hopping very well.

The analog setting circles on most inexpensive scopes are not very accurate. Compound that with errors in polar alignment and, more often than not, limited true fields of view and one can easily be a half of a degree or more off when using them to attempt to locate dim objects.

However, if a telescope has reasonably good analog setting circles, the technique of "offsetting" from bright stars works quite well.
