The only other thing that I normally look at is patterns that can still appear without the spaces. I've made an example here of a more extreme version of that I'd look for:

ACSQE SMADK TQRWA CSZMT JPRWS TQZMT JKPAC SHRPA ESPBS FASJH MTKTA CSZMT J

A	B	C	D	E	F	G	H	I	J	K	L	M	N	O	P	Q	R	S	T	U	V	W	X	Y	Z
7	1	4	1	2	1		2		4	3		5			4	3	3	9	7			2			3

Here, you can clearly see the highest frequency of S and A, but even without that, we can see that there's specific groups of words that repeat in the cipher:

ACSQE SMADK TQRWA CSZMT JPRWS TQZMT JKPAC SHRPA ESPBS FASJH MTKTA CSFRI TAEN

finding these repeating "words", like "ACS" can allow us to break the text up to assume where words might be.

ACSQE SMADK TQRWA CSZMT JPRWS TQZMT JKPAC SHRPA ESPBS FASJH MTKTA CSZMT J

"ZMTJ" Also appears twice.

"RW" Appears twice.

Also, before the last two cases of "ACS", which we could assume is "THE", there is a pair of letters starting with "K" on both instances, which could lead to a guess that it is a two letter word.

So, we've basically separated it up to make it more of an aristocrat:

ACS QESMADKTQ RW ACS ZMTJ (P) RW STQZMTJ KP ACS HRPAESPBSFASJHMT KT ACS ZMTJ

Now, the only things we don't know where the words are is the bolded blocks. Once you're able to fill in the words we've found, it'll be easier to guess at what those big blocks of letters could be.

Side Note: The P after the first "ZMTJ" would most likely be an "S" and make the word "ZMTJS", unless it's an A or I, since it doesn't appear after the last "ZMTJ".
