How to divide a two-dimensional array into four with ruby

Due to various reasons, I created a method that is profitable for everyone. I think the letters are refreshing, so I wrote a picture!

For example, suppose you have an arbitrary two-dimensional array like this. スクリーンショット 2020-12-26 14.20.49 2 2.png

I want to specify arbitrary coordinates as shown in (1,1) and divide it into four. スクリーンショット 2020-12-26 14.20.49.png

The code is here.

def divide_2d_array(array, x, y)
    temp1 = []
    temp2 = []
    array.each do |a|
        temp1 << a[0..y]
        temp2 << a[(y+1)..-1]
    a,c = temp1[0..x], temp1[(x+1)..-1]
    b,d = temp2[0..x], temp2[(x+1)..-1]
    return a,b,c,d

#I will try to run
arr = [[1,2,3],

p divide_2d_array(arr, 1, 1)
# =>[[[1, 2], [4, 5]], [[3], [6]], [[7, 8]], [[9]]]

It's done! !! !! Please let me know if there is a better way!
