Okay, let's tackle this math problem. We're starting with 885680 and subtracting 50365.

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

Step 2: We'll start by subtracting the digit 6 and the borrow 1 from 8 in column 2 and get 1.
1 is the next digit of our result.

Step 3: We'll start by subtracting the digit 3 and the borrow 0 from 6 in column 3 and get 3.
3 is the next digit of our result.

Step 4: We'll start by subtracting the digit 0 and the borrow 0 from 5 in column 4 and get 5.
5 is the next digit of our result.

Step 5: We'll start by subtracting the digit 5 and the borrow 0 from 8 in column 5 and get 3.
3 is the next digit of our result.

Step 6: We'll start by subtracting the digit 0 and the borrow 0 from 8 in column 6 and get 8.
8 is the next digit of our result.

So, 885680 - 50365 = 835315.
