Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
A rope has a length of 200 meters. Stefan cuts the rope into four equal parts, gives his mother half of the cut pieces, and subdivides the remaining pieces into two more equal parts. What's the length of each piece?

### Response:
When Stefan cuts the rope into four equal parts, he gets 200/4 = <<200/4=50>>50 meters of each piece.
Since he gives his mother half of the cut pieces, he remains with 1/2*4 = <<1/2*4=2>>2 pieces.
When he subdivides the remaining pieces, he gets 50/2 = <<50/2=25>>25 meters.
