This seems to work quite well:
((<.`(<.@%&10)@. (0=10&|) )^:_)"0] 12345024500000 1000001 0
123450245 1000001 0
I had another method involving q: and dividing by 10 ^ the
lesser of the powers of 2 and 5 in the factors, but it hangs J in
some circumstances!
You could also remove rightmost "0" characters in the
formatted representation(s) of the number(s),
eg
(#~-.@:((*/\.)@:('0'&=))) '12345024500000'
123450245
But it's a bit tricky to ensure you don't have
the representation in scientific notation,
eg
1.2345e13
