Here is a tough one:
Fill in the long division using the blanks and the given numbers.
Code:

---

              _ _ 8 _

       _______________

_ _ _ | _ _ _ _ _ _ 5 

        _ _ _ _

        ========

          _ _ _ _

            _ _ _ 

          ========

            _ _ _ _

              _ _ _

            ========

              _ _ _ _

              _ _ _ _

Took me about 5 minutes
Code:

---

              9 8 8 9

       _______________

1 1 5 | 1 1 3 7 2 3 5 

        1 0 3 5

        ========

          1 0 2 2

            9 2 0 

          ========

            1 0 2 3

              9 2 0

            ========

              1 0 3 5

              1 0 3 5

              ========

                    0

I cannot even understand SJ's question. Am I supposed to be able to comprehend the answer? *Goes back to playing with his abacus*

Okay, I'm an mechanical engineer and I really don't understand this sollution. How can 1023 minus 920 be 1035??????
Downright stupid if you ask me. But maybe I don't understand how it is put down. Please enlighten me.

Timstone, you've been using computers so long you've forgotten how to do long division.

1023 minus 920 is not 1035, it's 103. The 5 is brought down from the original number so you can do the next step in the process.

Yup, I discovered that too. But still the whole working of this sum eludes me. I can't grasp it. I must say I have only taken a quick look at it. I don't feel much for a thorough study of the phenomena.
