Solution 11968: Integer Division on the TI-89 Family, TI-92 Family, and Voyage™ 200 Graphing Calculators.
When I divide two integers, how can I get the quotient and remainder instead of a decimal answer or an improper fraction on the TI-89 family, TI-92 family, and Voyage 200 graphing calculators?
The TI-89 family, TI-92 family, and Voyage 200 do not have an integer division function that would return the quotient and remainder of a division of integers. However, a combination of the normal division and the remain( ) function can be used to calculate both the quotient and remainder.
For example, the division 123/32 will return 3.84375 in approximate mode. The number of units 3 is the quotient. To find the remainder, press [2nd] [MATH]  [ALPHA] [A] to select A:remain( then input 123, 32) and press [ENTER]; 27 is returned. So the division of 123/32 equals 3 with a remainder of 27 or 3 units 27/32.
For additional instructions on integer division and other operations, please see the TI-89 family, TI-92 family and Voyage 200 guidebooks.
