Okay, let's tackle this math problem. We're starting with 93861 and subtracting 88804.

Step 1: We'll start by subtracting the digit 4 and the borrow 0 from 1 in column 1 and get -3.
We add -3 to 10 and get 7 as the first digit of the result.

Step 2: We'll start by subtracting the digit 0 and the borrow 1 from 6 in column 2 and get 5.
5 is the next digit of our result.

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

Step 4: We'll start by subtracting the digit 8 and the borrow 0 from 3 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 8 and the borrow 1 from 9 in column 5 and get 0.
0 is the next digit of our result.

So, 93861 - 88804 = 5057.
