We can solve this together! We're beginning with 71715 and removing 16410 from it.

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

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

Step 3: We'll start by subtracting the digit 4 and the borrow 0 from 7 in column 3 and get 3.
3 is the next digit of our result.

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

Step 5: We'll start by subtracting the digit 1 and the borrow 1 from 7 in column 5 and get 5.
5 is the next digit of our result.

So, 71715 - 16410 = 55305.
