We can solve this together! We're beginning with 280158 and removing 38502 from it.

Step 1: We'll start by subtracting the digit 2 and the borrow 0 from 8 in column 1 and get 6.
6 is the first digit of our result.

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

Step 3: We'll start by subtracting the digit 5 and the borrow 0 from 1 in column 3 and get -4.
We add -4 to 10 and get 6 as the next digit of the result.

Step 4: We'll start by subtracting the digit 8 and the borrow 1 from 0 in column 4 and get -9.
We add -9 to 10 and get 1 as the next digit of the result.

Step 5: We'll start by subtracting the digit 3 and the borrow 1 from 8 in column 5 and get 4.
4 is the next digit of our result.

Step 6: We'll start by subtracting the digit 0 and the borrow 0 from 2 in column 6 and get 2.
2 is the next digit of our result.

So, 280158 - 38502 = 241656.
