Got it! So, we have 50479 and 26257, and we'll subtract the latter from the former.

Step 1: We'll start by subtracting the digit 7 and the borrow 0 from 9 in column 1 and get 2.
2 is the first digit of our result.

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

Step 3: We'll start by subtracting the digit 2 and the borrow 0 from 4 in column 3 and get 2.
2 is the next digit of our result.

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

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

So, 50479 - 26257 = 24222.
