Got it! So, we have 8471 and 4281, and we'll subtract the latter from the former.

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

Step 2: We'll start by subtracting the digit 8 and the borrow 0 from 7 in column 2 and get -1.
We add -1 to 10 and get 9 as the next digit of the result.

Step 3: We'll start by subtracting the digit 2 and the borrow 1 from 4 in column 3 and get 1.
1 is the next digit of our result.

Step 4: We'll start by subtracting the digit 4 and the borrow 0 from 8 in column 4 and get 4.
4 is the next digit of our result.

So, 8471 - 4281 = 4190.
