Splitting a text file by number of lines, not size

Question

Using Total Commander you can split files by byte size, but that's obviously indiscriminate towards the content.

Is it possible to split files by number of lines instead?

Using Total Commander or some other tool.

Using busybox head and tail will help

example sources, (you can cat or type or pipe your files):
busybox seq 1 100

first 50 lines:
busybox seq 1 100 | busybox head -50

last 50 lines:
busybox seq 1 100 | busybox tail -50

41^st to 50^th lines:
busybox seq 1 100 | busybox head -50 | busybox tail -10
