Iterate over $PATH variable using shell script

Question

If I type echo $PATH in the terminal I get the following result:

/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/home/fnorbert/.local/bin:/home/fnorbert/bin

I want to iterate over these paths using a shell script, but I do not know how to do that.
I tried the following:

for i in 1 2 3  
do
    echo $PATH | cut -d':' -f$i
done

This prints the first three paths, but I want to represent every path with the variable i if it is possible.

You can use read with delimiter set as :

while read -d ':' p; do
   echo "$p"
done <<< "$PATH:"
