No problem, let's work through this together. We're starting with 81592 and are subtracting 27948 from it.

Step 1: We'll start by subtracting the digit 8 and the borrow 0 from 2 in column 1 and get -6.
We add -6 to 10 and get 4 as the first digit of the result.

Step 2: We'll start by subtracting the digit 4 and the borrow 1 from 9 in column 2 and get 4.
4 is the next digit of our result.

Step 3: We'll start by subtracting the digit 9 and the borrow 0 from 5 in column 3 and get -4.
We add -4 to 10 and get 6 as the next digit of the result.

Step 4: We'll start by subtracting the digit 7 and the borrow 1 from 1 in column 4 and get -7.
We add -7 to 10 and get 3 as the next digit of the result.

Step 5: We'll start by subtracting the digit 2 and the borrow 1 from 8 in column 5 and get 5.
5 is the next digit of our result.

So, 81592 - 27948 = 53644.
