because if the remainder is larger then the divisor then you ate able to divide the remainder by the divisor 1 or how ever many
examples:29÷3.if you say 8r5 you can divide the remainder (5) by the divisor (3)one more time .so 29÷3=9r2.noe it is correct because you can't divide the remainder (2) by the divisor (3)
PS:I'm 10 and I'm in fifth grade.youre welcome.im happy to help.i love math
