Long Division
1. To demonstrate division by showing the working, let's use an example: divide 123 by 3.
2. Write the division as $123 \div 3$.
3. Start dividing from the leftmost digit: 1 divided by 3 is 0 times since 1 is less than 3.
4. Take the first two digits: 12 divided by 3 equals 4 because $3 \times 4 = 12$.
5. Write 4 above the division bar.
6. Subtract $12$ from $12$, resulting in 0.
7. Bring down the next digit, 3.
8. Divide 3 by 3 equals 1 because $3 \times 1 = 3$.
9. Write 1 next to 4 above the division bar.
10. Subtract $3$ from $3$, resulting in 0.
11. There are no digits left to bring down, and the remainder is 0.
12. The quotient is $41$.
Final answer: $$123 \div 3 = 41$$
