Let's get this math done. We have 925700439 and 354908022, and we're going to subtract the second number from the first.

Step 1: We'll start by subtracting the digit 2 and the borrow 0 from 9 in column 1 and get 7.
7 is the first digit of our result.

Step 2: We'll start by subtracting the digit 2 and the borrow 0 from 3 in column 2 and get 1.
1 is the next digit of our result.

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

Step 4: We'll start by subtracting the digit 8 and the borrow 0 from 0 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 0 in column 5 and get -1.
We add -1 to 10 and get 9 as the next digit of the result.

Step 6: We'll start by subtracting the digit 9 and the borrow 1 from 7 in column 6 and get -3.
We add -3 to 10 and get 7 as the next digit of the result.

Step 7: We'll start by subtracting the digit 4 and the borrow 1 from 5 in column 7 and get 0.
0 is the next digit of our result.

Step 8: We'll start by subtracting the digit 5 and the borrow 0 from 2 in column 8 and get -3.
We add -3 to 10 and get 7 as the next digit of the result.

Step 9: We'll start by subtracting the digit 3 and the borrow 1 from 9 in column 9 and get 5.
5 is the next digit of our result.

So, 925700439 - 354908022 = 570792417.
