OK, let's do this. We've got 882227275 and 817884851, and we're subtracting the second number from the first.

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

Step 2: We'll start by subtracting the digit 5 and the borrow 0 from 7 in column 2 and get 2.
2 is the next digit of our result.

Step 3: We'll start by subtracting the digit 8 and the borrow 0 from 2 in column 3 and get -6.
We add -6 to 10 and get 4 as the next digit of the result.

Step 4: We'll start by subtracting the digit 4 and the borrow 1 from 7 in column 4 and get 2.
2 is the next digit of our result.

Step 5: We'll start by subtracting the digit 8 and the borrow 0 from 2 in column 5 and get -6.
We add -6 to 10 and get 4 as the next digit of the result.

Step 6: We'll start by subtracting the digit 8 and the borrow 1 from 2 in column 6 and get -7.
We add -7 to 10 and get 3 as the next digit of the result.

Step 7: We'll start by subtracting the digit 7 and the borrow 1 from 2 in column 7 and get -6.
We add -6 to 10 and get 4 as the next digit of the result.

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

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

So, 882227275 - 817884851 = 64342424.
