We can solve this together! We're beginning with 93089 and removing 15843 from it.

Step 1: We'll start by subtracting the digit 3 and the borrow 0 from 9 in column 1 and get 6.
6 is the first digit of our result.

Step 2: We'll start by subtracting the digit 4 and the borrow 0 from 8 in column 2 and get 4.
4 is the next digit of our result.

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

Step 4: We'll start by subtracting the digit 5 and the borrow 1 from 3 in column 4 and get -3.
We add -3 to 10 and get 7 as the next digit of the result.

Step 5: We'll start by subtracting the digit 1 and the borrow 1 from 9 in column 5 and get 7.
7 is the next digit of our result.

So, 93089 - 15843 = 77246.
