Try...
Code:
split -l 25000 yourinputfile

Here -l is -{small letter L} and above command will make following four files, in the same directory:
Code:
xaa ---->First 25,000 Lines
xab  ---->25-50000 Lines
xac ----->50-75000 Lines
xad ----->75-90000 Lines

Regards,
Tayyab

What you mean by operating system format? If you identify a .txt file as text file, rename split generated files to .txt like xaa to xaa.txt. Otherwise post here the top 100 hundred lines of your input file and output of 2 files generated with following commands:
Code:
head +100 yourinputfile > tempfile
split -l 50 tempfile

Altenative in Python:
Code:
all = open("file_with_records.txt").readlines()
open("file0-25000.txt","w").write( ''.join(all[0:25000] )  )
open("file25001-50000.txt","w").write( ''.join(all[25001:50000] ) )
open("file50001-75000.txt","w").write( ''.join(all[50001:75000] ) )
open("file75001-90000.txt","w").write( ''.join(all[75000:] ) )

I can't help any more, I think you miss quite a few basic concepts, and I'm not sure how you are checking the properties of file and trying to display the contents of the file, by the way which operating system you are using and how you executed the above split command, how you checked the properties of split generated files? Don't go for file extensions, just try to view the contents of the file using cat command, don't worry split will generate an ASCII file against an ASCII file input.
