Following Hans' logic, here is the modified version of the \breaklonglines:

\def\breaklongline#1{%
\@tfor\@breakchar:=#1\do{%
\@breakchar\allowbreak}%
}

\breakline takes only one argument of the long numbers which it scans
every digit and adds an \allowbreak after each digit which will makes it
possible to typeset without any hassles.
