the calculus of paranoïd, my dear Watson

in fact square dates are silly, and you won't get one in Diy easily, but
reading of squares, and factors, some months (79 crosswords to be exact)

I puzzled on a method to do fractional divisions on paper, that is without
the aid of 29th century tech. so for a test I wrote down two random
numbers:

18342 / 0.42832

or, as in primary school,

0.42832 / 18342 \ = ?

never mind the method, I'll re: it to you if you like, the answer turned
out
to be

0.42832 / 18342 \ 42823

now what are the chances of that?????? a real number would be fine. bear
in
mind that the chance of something happening by coïncidence is defined by
multiplication of the chances of all constituent factors of the event, and
with the rising of the number of factors that chance would rather rapidly
decrease onto 0, slashed or not. and that the chance of it happening by
some
form of design (i.e. on purpose) would be the complement ot the result to
a
total probability of 1 (design = 1 - coïncidence).
