I remember a while back I dealt with that problem for 83/83+.  This is the 
code I came up with (obviously, its 83(+) basic, but it shouldn't be too 
hard to convert to 85/86).  It's been a while since I've used it, but it 
should be nicely optimized and it will work for any number (integer, 
fraction, whatever) with a finite number of decimal places.  Although, it 
might take a little while to do a 99-place decimal...  If you stick to 
reasonable numbers, like 5 or 2.74, it should be quite fast.  Obviously, if 
you'll be using this as a subroutine in a program, you might find removing 
the prompt and disp commands useful.

Prompt X
X->Y:0->M
Repeat iPart(Y)=0
Y/10->Y
M+1->M
End
X/10^(M-1)->Y
iPart(Y)->X
sub("0123456789",X+1,1)->Str1
Y-X->Y
10Y->Y
1->Z
Repeat Y=0
If Z=M
Str1+"."->Str1
iPart(Y)->X
Str1+sub("0123456789",X+1,1)->Str1
Y-X->Y
10Y->Y
Z+1->Z
End
Disp Str1

Enjoy.
