Seriously..

1.Chose whatever range, like I said, for the moment I have tested until puzzle 130, generate Yourself a hex private key in between chosen range and get the address.
2 Convert the hash160 of that address to decimal string.
3.Convert the hexadecimal private key to decimal as well,
4 Now using a big integer calculator for example http://www.javascripter.net/math/calculators/100digitbigintcalculator.htm ( I am also using it ) divide the decimal string of hash160 by decimal version of private key
5.The resulting string now You have to multiply times decimal private key.
6 That multiplication will result with a long string of course but quite similar with the first digits like so basically that string will be required by me.
