It is important to get a non-zero leading coefficient. If it becomes zero, the row gets swapped with a lower one with a non-zero coefficient in the same position.

See Answer lyrics usher burnA variation of the partial pivoting strategy is scaled pivoting. In this approach, the algorithm selects as the pivot element the entry that is largest relative to the entries in its row. This strategy is desirable when entries' large differences in magnitude lead to the propagation of round-off error.
