If the number is 3.8333333.... then

X=3.83333....
10X = 38.3333.....

10X - X
  38.3333....
  - 3.8333....
= 34.5
so 9X = 34.5
X = 34.5/9
Multiple both top and bottom by 2 to get rid of decimal.
69/18
Normalize it to get rid of improper fraction.
3  15/18
Simplify
3  5/6

If the number is 3.838383838383.... then
      X =     3.83838383...
100X = 383.83838383...

100X - X = 99X
383.83838383...
    3.83838383...
380

99X = 380
X = 380/99

X = 3  83/99
