Total number of apples harvested = 5472
Number of apple trees = 12
Since all the apple trees have produced equal number of apples, we need to divide 5472 by 12 to get the number of apples produced of each of them.

\begin{array}{c}

12\enclose{longdiv}{5472} \\[-3pt]

\end{array}
Thus, the apple trees produced 456 apples each.
