I hope this will help you ( I wrote a console program  and tested which will give you the result required,
-------------
// byte representation of a long number
int a = 123456789; //111 01011011 11001101 00010101
byte []b = new byte[4];
b[0] = (byte)(a & 0xFF);
b[1] = (byte)((a & 0xFF00) >>8);
b[2] = (byte)((a & 0xFF0000) >> 16);
b[3] = (byte) ((a & 0xFF000000) >>24);
Console.WriteLine(b[0]);
Console.WriteLine(b[1]);
Console.WriteLine(b[2]);
Console.WriteLine(b[3]);
----------------------
b[0] is and'ing with 255 so get the first byte
b[1] is and'ing only 2'nd byte and rest are zero'ed and then right shifted 8 bytes so as to get byte what's in it.
and so on.

Programmers aren't born, but are made from hardwork, effort and time.
To be a good one, requires more effort and hardwork.
Therefore N quality programmer = (N*hardwork)+(N*effort)+(N*time)

Hay you guys! Have you ever heart about the windows socket function like: ntohl()? It takes big indian long and conerts it into the little-indian on Intel processors...
You can import them into the C# and use them...
I know, it is just alternative and the paresh's solution works too...

Hm... If this is the point (to make things more difficult), I would recommed him to write the routine in LISP and use it in C#...
Or even better, to use monolit microcomputer, write it in assembler and comunicatate with the monolit mc using COM port...
