Alright, let's solve this problem step by step. We have 930800094 and 416575878, and we're subtracting the second number from the first.

Step 1: We'll start by subtracting the digit 8 and the borrow 0 from 4 in column 1 and get -4.
We add -4 to 10 and get 6 as the first digit of the result.

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

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

Step 4: We'll start by subtracting the digit 5 and the borrow 1 from 0 in column 4 and get -6.
We add -6 to 10 and get 4 as the next digit of the result.

Step 5: We'll start by subtracting the digit 7 and the borrow 1 from 0 in column 5 and get -8.
We add -8 to 10 and get 2 as the next digit of the result.

Step 6: We'll start by subtracting the digit 5 and the borrow 1 from 8 in column 6 and get 2.
2 is the next digit of our result.

Step 7: We'll start by subtracting the digit 6 and the borrow 0 from 0 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 1 and the borrow 1 from 3 in column 8 and get 1.
1 is the next digit of our result.

Step 9: We'll start by subtracting the digit 4 and the borrow 0 from 9 in column 9 and get 5.
5 is the next digit of our result.

So, 930800094 - 416575878 = 514224216.
