  The first aim of this note is to fill a gap in the literature by proving
that, given a global field $K$ and a finite set $\mathcal{S}$ of primes of $K$,
every finite split embedding problem $G \rightarrow {\rm{Gal}}(L/K)$ over $K$
with nilpotent kernel has a solution ${\rm{Gal}}(F/K) \rightarrow G$ such that
all primes in $\mathcal{S}$ are totally split in $F/L$. We then apply this to
inverse Galois theory over division rings. Firstly, given a number field $K$ of
level at least $4$, we show that every finite solvable group occurs as a Galois
group over the division ring $H_K$ of quaternions with coefficients in $K$.
Secondly, given a finite split embedding problem with nilpotent kernel over a
finite field $K$, we fully describe for which automorphisms $\sigma$ of $K$ the
embedding problem acquires a solution over the skew field of fractions $K(T,
\sigma)$ of the twisted polynomial ring $K[T, \sigma]$.
