Let's get this math done. We have 713872060 and 169009919, and we're going to subtract the second number from the first.

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

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

Step 3: We'll start by subtracting the digit 9 and the borrow 0 from 0 in column 3 and get -9.
We add -9 to 10 and get 1 as the next digit of the result.

Step 4: We'll start by subtracting the digit 9 and the borrow 1 from 2 in column 4 and get -8.
We add -8 to 10 and get 2 as the next digit of the result.

Step 5: We'll start by subtracting the digit 0 and the borrow 1 from 7 in column 5 and get 6.
6 is the next digit of our result.

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

Step 7: We'll start by subtracting the digit 9 and the borrow 0 from 3 in column 7 and get -6.
We add -6 to 10 and get 4 as the next digit of the result.

Step 8: We'll start by subtracting the digit 6 and the borrow 1 from 1 in column 8 and get -6.
We add -6 to 10 and get 4 as the next digit of the result.

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

So, 713872060 - 169009919 = 544862141.
