To perform long division for 9 divided by 840, you would write 9 as the dividend inside the division bracket and 840 as the divisor outside the bracket. The first step would be to determine how many times 9 can go into 84 (the first two digits of 840), which is 9 times. You then multiply 9 by 9 to get 81 and subtract it from 84 to get a remainder of 3. Since there are no more digits to bring down, the final answer is 9 with a remainder of 3, which can be expressed as 9.3 or 9 3/840.
