Got it! So, we have 35752 and 509, and we'll subtract the latter from the former.

Step 1: We'll start by subtracting the digit 9 and the borrow 0 from 2 in column 1 and get -7.
We add -7 to 10 and get 3 as the first digit of the result.

Step 2: We'll start by subtracting the digit 0 and the borrow 1 from 5 in column 2 and get 4.
4 is the next digit of our result.

Step 3: We'll start by subtracting the digit 5 and the borrow 0 from 7 in column 3 and get 2.
2 is the next digit of our result.

Step 4: We'll start by subtracting the digit 0 and the borrow 0 from 5 in column 4 and get 5.
5 is the next digit of our result.

Step 5: We'll start by subtracting the digit 0 and the borrow 0 from 3 in column 5 and get 3.
3 is the next digit of our result.

So, 35752 - 509 = 35243.
