using (System.IO.StreamReader sr = new System.IO.StreamReader("path"))
{
    int fileNumber = 0;

    while (!sr.EndOfStream)
    {
        int count = 0;

        using (System.IO.StreamWriter sw = new System.IO.StreamWriter("other path" + ++fileNumber))
        {
            sw.AutoFlush = true;

            while (!sr.EndOfStream && ++count < 20000)
            {
                sw.WriteLine(sr.ReadLine());
            }
        }
    }
}
