We can solve this together! We're beginning with 60490 and removing 60370 from it.

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

Step 2: We'll start by subtracting the digit 7 and the borrow 0 from 9 in column 2 and get 2.
2 is the next digit of our result.

Step 3: We'll start by subtracting the digit 3 and the borrow 0 from 4 in column 3 and get 1.
1 is the next digit of our result.

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

Step 5: We'll start by subtracting the digit 6 and the borrow 0 from 6 in column 5 and get 0.
0 is the next digit of our result.

So, 60490 - 60370 = 120.
