Alright, let's solve this problem step by step. We have 25070 and 19457, and we're subtracting the second number from the first.

Step 1: We'll start by subtracting the digit 7 and the borrow 0 from 0 in column 1 and get -7.
We add -7 to 10 and get 3 as the first digit of the result.

Step 2: We'll start by subtracting the digit 5 and the borrow 1 from 7 in column 2 and get 1.
1 is the next digit of our result.

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

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

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

So, 25070 - 19457 = 5613.
