Function ramp::ll::divrem

pub unsafe fn divrem(
    qp: LimbsMut, 
    rp: LimbsMut, 
    np: Limbs, 
    ns: i32, 
    dp: Limbs, 
    ds: i32
)

Divides {np, ns} by {dp, ds}. If ns <= ds, the quotient is stored in {qp, 1}, otherwise the quotient is stored to {qp, (ns - ds) + 1}. The remainder is always stored to {rp, ds}.
