The division of a whole given in intuition is a regress from something conditioned to the conditions of its possibility. Contrast this with first cosmological idea where the conditions were met with outside the conditioned. The regress, therefore, proceeds in infinitum . We cannot, however, say of a whole which is divisible to infinity, that it is made up of infinitely many parts. Although the parts are contained in the intuition of the whole, the whole division is not so contained.
Every space is therefore infinitely divisible.
Body, which is grounded in the divisibility of space, is therefore infinitely divisible without consisting, however, of infinitely many parts. We have been overlooking the distinction between mathematical and dynamical syntheses of appearance. In the dynamical, there may be a presupposition compatible with the pretensions of reason. In the dynamical series of sensible conditions, a heterogeneous condition, not itself a part of the series, but purely intelligible, and as such outside the series, can be allowed. The empirically unconditioned is also non-sensible and therefore can satisfy understanding and reason.
