Let's dive into this subtraction. We'll start with 2608 and subtract 1265 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 0 in column 2 and get -6.
We add -6 to 10 and get 4 as the next digit of the result.

Step 3: We'll start by subtracting the digit 2 and the borrow 1 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 1 and the borrow 0 from 2 in column 4 and get 1.
1 is the next digit of our result.

So, 2608 - 1265 = 1343.
