No problem, let's work through this together. We're starting with 627069 and are subtracting 67510 from it.

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

Step 2: We'll start by subtracting the digit 1 and the borrow 0 from 6 in column 2 and get 5.
5 is the next digit of our result.

Step 3: We'll start by subtracting the digit 5 and the borrow 0 from 0 in column 3 and get -5.
We add -5 to 10 and get 5 as the next digit of the result.

Step 4: We'll start by subtracting the digit 7 and the borrow 1 from 7 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 6 and the borrow 1 from 2 in column 5 and get -5.
We add -5 to 10 and get 5 as the next digit of the result.

Step 6: We'll start by subtracting the digit 0 and the borrow 1 from 6 in column 6 and get 5.
5 is the next digit of our result.

So, 627069 - 67510 = 559559.
