Sure thing! We've got 670153412 and 223289729, 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 2 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 2 and the borrow 1 from 1 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 7 and the borrow 1 from 4 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 3 in column 4 and get -7.
We add -7 to 10 and get 3 as the next digit of the result.

Step 5: We'll start by subtracting the digit 8 and the borrow 1 from 5 in column 5 and get -4.
We add -4 to 10 and get 6 as the next digit of the result.

Step 6: We'll start by subtracting the digit 2 and the borrow 1 from 1 in column 6 and get -2.
We add -2 to 10 and get 8 as the next digit of the result.

Step 7: We'll start by subtracting the digit 3 and the borrow 1 from 0 in column 7 and get -4.
We add -4 to 10 and get 6 as the next digit of the result.

Step 8: We'll start by subtracting the digit 2 and the borrow 1 from 7 in column 8 and get 4.
4 is the next digit of our result.

Step 9: We'll start by subtracting the digit 2 and the borrow 0 from 6 in column 9 and get 4.
4 is the next digit of our result.

So, 670153412 - 223289729 = 446863683.
