I recently read that this formula,
(Number / 10^K-1) % 10
Edit: updated formula to use K-1
Will give me the Kth digit of Number.
For example if i want the 2nd digit from 345, I have (345/100)%10 which gives 4.
Why does this work? 🤔

Either you start counting the first number as the 0th number or it is (k-1)
n / 10^k cuts of k numbers on the right (assuming division with round down)
and the % 10 cuts of everything left of the ones-digit
