Alright, let's solve this problem step by step. We have 968249193 and 687328092, and we're subtracting the second number from the first.

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

Step 2: We'll start by subtracting the digit 9 and the borrow 0 from 9 in column 2 and get 0.
0 is the next digit of our result.

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

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

Step 5: We'll start by subtracting the digit 2 and the borrow 0 from 4 in column 5 and get 2.
2 is the next digit of our result.

Step 6: We'll start by subtracting the digit 3 and the borrow 0 from 2 in column 6 and get -1.
We add -1 to 10 and get 9 as the next digit of the result.

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

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

Step 9: We'll start by subtracting the digit 6 and the borrow 1 from 9 in column 9 and get 2.
2 is the next digit of our result.

So, 968249193 - 687328092 = 280921101.
