323 divided by 17 is 19. Start with the first two digits: 17 goes into 32 how many times? Once with 15 remainder. Take the 15 and tack it onto the last digit (3) to get 153 and then ask: how many times does 17 go into 153? Well we know that 17 goes into 170 ten times. And we know that the difference between 153 and 170 is 17. Therefore 17 goes into 153 one less time than ten which is the same as saying 17 goes into 153 nine times. Since we know that 17 goes into the first two digits of 323 once and the remainder plus the last digit (153) nine times, we put the 1 and the 9 together to make 19. 17 goes into 323 nineteen times: 323/17=19
