Summation, modulo and decimal

Hello.
I'm trying to use the modulo (modulus, mod, %) to do the following:
(1) 0,147536 -> (2) 0.101110
The problem is that modulo is only def. to Integers. So, I used the
sigma/summation to shift the decimal point to the left (multiply by
10^k) to get each digit. It not worked because before it shift the
digit to the left the number is added to the previous value, so, I used
in the formula another "trick" (-1)^k , so the number stay the same
after k even increments. When I try to use it all together the (-1)^k
and the 10^k "cancel each other" and I get the same initial value.
What´s wrong with my logic?
How can I use the Sum and Mod to turn each number to 1´s and 0´s
giving a number, say, 3,14231243545546 ? I know how to do it using c++
and other languages but I want to make it using only mathematics tools.
Thank you all for the attention,
Spin.
