Got it! So, we have 84937 and 55838, and we'll subtract the latter from the former.

Step 1: We'll start by subtracting the digit 8 and the borrow 0 from 7 in column 1 and get -1.
We add -1 to 10 and get 9 as the first digit of the result.

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

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

Step 4: We'll start by subtracting the digit 5 and the borrow 0 from 4 in column 4 and get -1.
We add -1 to 10 and get 9 as the next digit of the result.

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

So, 84937 - 55838 = 29099.
