How to split a file into smaller files

Hi,
I have a big text file with m columns and n rows. The format is like:

STF123450001000200030004STF123450005000600070008STF123450009001000110012
STF234560345002208330154STF234590705620600070080STF234567804094562357688
STF356780001000200030004STF356780005000600070080STF356780800094562657687
....
....
....
....

What I want is read the file, split the first line, write the first STF section to file1 and second STF section to file 2 and so on; then read the second line, append the first STF section to file1 as the second line and second STF section to file2 as the second line and so on....

Thanks!

NAME
paste - paste multiple files together SYNOPSIS
paste [-s] [-d list] file... OPTIONS
-d Set delimiter used to separate columns to list. -s Print files sequentially, file k on line k. EXAMPLES
paste file1 file2 # Print file1 in col 1, file2 in col 2 paste -s f1 f2 # Print f1 on line 1 and f2 on line 2 paste -d : file1 file2 # Print the lines separated by a colon DESCRIPTION
Paste concatenates corresponding lines of the given input files and writes them to standard output. The lines of the different files are separated by the delimiters given with the option -s. If no list is given, a tab is substituted for every linefeed, except the last one. If end-of-file is hit on an input file, subsequent lines are empty. Suppose a set of k files each has one word per line. Then the paste output will have k columns, with the contents of file j in column j. If the -s flag is given, then the first file is on line 1, the second file on line 2, etc. In effect, -s turns the output sideways. If a list of delimiters is given, they are used in turn. The C escape sequences , , \, and are used for linefeed, tab, backslash, and the null string, respectively. PASTE(1)
