To do this, you must divide 15,908 by 13. 13 goes into 15 one time, and 15 minus 13 is 2. Carry down the 9 to make 29, and 13 goes into 29 two times, which is 26. 29 minus 26 equals 3, and carry down the 0 to make 30. 13 goes into 30 two times, which is 26. 30 minus 26 equals 4, and carry down the 8 to make 48. 13 times 3 equals 39, and 48 minus 39 equals 9. 15,908 divided by 13 gives you 1223 with a remainder of 9.
