The division bar ( 厂 ) looks like an ending parentheses attached to a horizontal line that goes over the string of numbers beneath the bar. Place the divisor, the number you'll be dividing, outside the long division bar, and the dividend, the number that you'll be dividing into, inside the long division bar.   Sample problem #1 (beginner): 65 ÷ 5. Place the 5 outside the division bar, and the 65 inside it. It should look like 5厂65, but with the 65 underneath the horizontal line. Sample problem #2 (intermediate): 136 ÷ 3. Place the 3 outside the division bar, and the 136 inside it. It should look like 3厂136, but with the 136 underneath the horizontal line. In other words, figure out how many times the divisor (the number outside the division bar) goes into the first digit of the dividend. Place the whole number result above the division line, right above the first digit of the divisor.  In sample problem #1 (5厂65), 5 is the divisor and 6 is the first digit of the dividend (65). 5 goes into 6 one time, so place a 1 on the top of the divisor bar, aligned above the 6. In sample problem #2 (3厂136), 3 (the divisor) does not go into 1 (the first digit of the dividend) and result in a whole number. In this case, write a 0 above the division bar, aligned above the 1. Take the number you just wrote above the division bar and multiply it by the divisor (the number to the left of the division bar). Write the result in a new row beneath the dividend, aligned with the first digit of the dividend.  In sample problem #1 (5厂65), multiply the number above the bar (1) by the divisor (5), which results in 1 x 5 = 5, and place the answer (5) just below the 6 in 65. In sample problem #2 (3厂136), there is a zero above the division bar, so when you multiply this by 3 (the divisor), your result is zero. Write a zero on a new line just below the 1 in 136. In other words, subtract the number you just wrote in the new row below the dividend from the digit in the dividend directly above it. Write the result in a new row, in alignment with the digits from the subtraction problem.  In sample problem #1 (5厂65), subtract the 5 (the multiplication result in the new row) from the 6 right above it (the first digit of the dividend): 6 - 5 = 1. Place the result (1) in a another new row right below the 5. In sample problem #2 (3厂136), subtract 0 (the multiplication result in the new row) from the 1 right above it (the first digit in the dividend). Place the result (1) in another new row right below the 0. Drop down the second digit of the dividend to the new bottom row, just to the right of the subtraction result you just got.  In sample problem #1 (5厂65), drop the 5 from 65 down so that it’s beside the 1 that you got from subtracting 5 from 6. This gives you 15 in this row. In sample problem #2 (3厂136), carry down the 3 from 136 and place it beside the 1, giving you 13. This time, use the dividend (the number to the left of the division bar) and the new number on the bottom row (the result of your first round of calculations and the digit you carried down). As before, divide, then multiply, and finally subtract to get your result.  To continue 5厂65, divide 5 (the dividend) into the new number (15), and write the result (3, since 15 ÷ 5 = 3) to the right of the 1 above the division bar. Then, multiply this 3 above the bar by 5 (the dividend) and write the result (15, since 3 x 5 = 15) below the 15 under the division bar. Finally, subtract 15 from 15 and write 0 in a new bottom row. Sample problem #1 is now complete, since there are no more digits in the divisor to carry down. Your answer (13) is above the division bar. Like before, you start by dividing, then multiply, and finish up by subtracting. For 3厂136: Determine how many times 3 goes into 13, and write the answer (4) to the right of the 0 above the division bar. Then, multiply 4 by 3 and write the answer (12) below the 13. Finally, subtract 12 from 13 and write the answer (1) below the 12. When you’ve finished this problem, take note that there is a remainder (that is, a number left over at the end of your calculating). You'll place this remainder beside your whole number answer.  For 3厂136: Continue the process for another round. Drop down the 6 from 136, making 16 in the bottom row. Divide 3 into 16, and write the result (5) above the division line. Multiply 5 by 3, and write the result (15) in a new bottom row. Subtract 15 from 16, and write the result (1) in a new bottom row. Because there are no more digits to carry down in the dividend, you’re done with the problem and the 1 on the bottom line is the remainder (the amount left over). Write it above the division bar with an “r.” in front of it, so that your final answer reads “45 r.1”.
