Let's get this math done. We have 774748057 and 441066171, and we're going to subtract the second number from the first.

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

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

Step 3: We'll start by subtracting the digit 1 and the borrow 1 from 0 in column 3 and get -2.
We add -2 to 10 and get 8 as the next digit of the result.

Step 4: We'll start by subtracting the digit 6 and the borrow 1 from 8 in column 4 and get 1.
1 is the next digit of our result.

Step 5: We'll start by subtracting the digit 6 and the borrow 0 from 4 in column 5 and get -2.
We add -2 to 10 and get 8 as the next digit of the result.

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

Step 7: We'll start by subtracting the digit 1 and the borrow 0 from 4 in column 7 and get 3.
3 is the next digit of our result.

Step 8: We'll start by subtracting the digit 4 and the borrow 0 from 7 in column 8 and get 3.
3 is the next digit of our result.

Step 9: We'll start by subtracting the digit 4 and the borrow 0 from 7 in column 9 and get 3.
3 is the next digit of our result.

So, 774748057 - 441066171 = 333681886.
