Sure thing! We've got 99186 and 84464, and we're going to subtract the second number from the first.

Step 1: We'll start by subtracting the digit 4 and the borrow 0 from 6 in column 1 and get 2.
2 is the first digit of our result.

Step 2: We'll start by subtracting the digit 6 and the borrow 0 from 8 in column 2 and get 2.
2 is the next digit of our result.

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

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

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

So, 99186 - 84464 = 14722.
