Base 30 (= 2 × 3 × 5) has exactly the same exact divisors.
 
There is no point in repeating prime factors in the base.

 
30 / 4  = ...?
30 / 12 = ...?
30 / 20 = ...?

Using letters a .. t to represent the 20 additional digits, in base-30
these become

10 ÷ 4 = 7.f0

10 ÷ c = 2.f0

10 ÷ k = 0.f0

Try something a bit less simplistic?

1 ÷ 3 = 0.a

All these fractions are exact -- no repeating digits.
