I feel you, my husband still isn't here and we started this process 5/4/17

Receiving a 221g is not "normal" administrative processing. It indicates they are doing further background checks than they would normally do otherwise. There's really no way to find out what the hold up is, or when they might be ready to issue the visa. My fiancé received the 221g at his interview in September 2018 and we have had no updates since. I would guess in your case, it may have something to do with your previous marriage. I wouldn't stress about it, many are receiving 221g's right now. It will just take some extra time, but the visa should eventually be issued.

many of us wonder why some spouses of even USC get approved at interview and others get handed the same form your now wife got handed
 
its part of the process, but still have no rhyme or reason to it.
 
for example my husband got handed a 221G paper for AP, no other documents, someone came in a few weeks after him had interview, tons of red flags got approved on the spot.
 
you just never know and trying to get in the head of a CO will only drive you crazy
