Dividing Dollar Amounts Unevenly Into Varying Numbers Of Cells/columns

I have dollar amounts that I need to distribute amongst varying numbers of columns and not have have the total distributed be over or under the original amount by any number of cents. When I simply divide the dollar amount by the number of columns, the total of those columns can sometimes be more or less than the original dollar amount by a few cents.


e.g.
Dollar # of A B C All Columns
Amount Columns Total
--------------------------------------------------------------------
$25.05 2 $12.53 $12.53 $25.06
$11.47 3 $ 3.82 $ 3.82 $ 3.82 $11.46
$25.05 divided into 2 columns gives $12.53 in Column A and $12.53 in Column B. Total of Columns A and B is $25.06. Over by a penny.

$11.47 divided into 3 columns gives $3.82 in Columns A through C. Total of Columns A through C is $41.46. Under by a penny.

I know I could simply always add or take away the pennies from one column, but I would prefer the process to be random or formulated in such a way that the Column to which the extra pennies are added to or taken away from differs in order to be "fair to each column".
