We can solve this together! We're beginning with 24478 and removing 8161 from it.

Step 1: We'll start by subtracting the digit 1 and the borrow 0 from 8 in column 1 and get 7.
7 is the first digit of our result.

Step 2: We'll start by subtracting the digit 6 and the borrow 0 from 7 in column 2 and get 1.
1 is the next digit of our result.

Step 3: We'll start by subtracting the digit 1 and the borrow 0 from 4 in column 3 and get 3.
3 is the next digit of our result.

Step 4: We'll start by subtracting the digit 8 and the borrow 0 from 4 in column 4 and get -4.
We add -4 to 10 and get 6 as the next digit of the result.

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

So, 24478 - 8161 = 16317.
