Game Feature

I know this is the representation of bar pieces and off pieces for the player but why divide by two in the first one and num_pieces in the second ? What this means?
features.append(float(len(self.bar_pieces[p])) / 2.)
features.append(float(len(self.off_pieces[p])) / self.num_pieces[p])

and in the training why feed V_next like this:
_, global_step, summaries, _ = self.sess.run(
[self.train_op, self.global_step, self.summaries_op, self.reset_op],
feed_dict={self.x: x, self.V_next: np.array([[winner]], dtype="float")},
?
