We can solve this together! We're beginning with 58778 and removing 57865 from it.

Step 1: We'll start by subtracting the digit 5 and the borrow 0 from 8 in column 1 and get 3.
3 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 8 and the borrow 0 from 7 in column 3 and get -1.
We add -1 to 10 and get 9 as the next digit of the result.

Step 4: We'll start by subtracting the digit 7 and the borrow 1 from 8 in column 4 and get 0.
0 is the next digit of our result.

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

So, 58778 - 57865 = 913.
