Write a program to print the quotient and remainder on dividing sum of left-top to right-bottom diagonal by sum of right-top to left-bottom diagonal.

Sure, here is a Python program that does that:

def diagonal_sum(matrix):
    # Initialize sums of diagonals
    d1 = d2 = 0
    n = len(matrix)

    for i in range(0, n):
        for j in range(0, n):
            # finding sum of primary diagonal
            if (i == j):
                d1 += matrix[i][j]

            # finding sum of secondary diagonal
            if (i == n - j - 1):
                d2 += matrix[i][j]

    # printing the result
    if d2 != 0:
        print("Quotient is", d1 // d2)
        print("Remainder is", d1 % d2)
    else:
        print("Cannot divide by zero")

# Test the function
matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
diagonal_sum(matrix)

This program first calculates the sum of the elements in the left-top to right-bottom diagonal (primary diagonal) and the right-top to left-bottom diagonal (secondary diagonal) of the matrix. Then it prints the quotient and remainder of the division of the sum of the primary diagonal by the sum of the secondary diagonal. If the sum of the secondary diagonal is zero, it prints a message saying that division by zero is not possible.
