we have that
0.04524/0.0078
we know that
0.04524--------> is equal to 4524 x 10^-5
0.0078---------> is equal to 78 x 10^-4
(4524 x 10^-5)/(78 x 10^-4)----> (4524/78) x 10^(-5+4)---> (4524/78) x 10^-1
4524/78----> divided by 2------> 2262/39
2262/39-----> divided by 3-----> 754/13----> 58
therefore
(4524/78) x 10^-1------> (58) x 10^-1------> 5.8
the answer is
5.8
