To divide 66 by 5, we can follow these steps:
-
How many groups? 5
-
Divide the tens: We have 60 (which is 6 tens). Dividing 60 by 5 gives us 12. Each of the five groups gets 12.
-
Regroup the extra tens block into ones: After taking care of the tens, we are left with 6 (since 66 - 60 = 6), which is the remaining ones. There are no extra tens remaining to regroup, but we do have these 6 ones.
-
Disperse these ones pieces evenly: Distributing the 6 ones among the 5 groups gives us 1 extra one in each of 5 groups, with 1 left over.
-
Our answer is: 13 remainder 1 (since 12 from the tens + 1 from the ones = 13, and there is 1 left over).
So, 66 divided by 5 equals 13 remainder 1.
