Division by zero

In the world of numbers,
There is a lovely number, zero.
It won’t bother others by adding and subtracting
However,
It makes a number disappear by multiplying.
It is very welcomed if it is added to people’s saving account:
100,
1000,
10,000,
100,000,
1,000,000,
10,000,000,
…
But it is hated while appearing to people’s credit cards.
In an elementary school,
As a divisor,
It is loved by kids if it follows a one,
10,
“It is easy,just move the dividend decimal point one place to the left”, the kids said.
However, if the one is gone, the kids will look at the divisor,
0
“What is the answer a number divided by zero?” the kids are confusing?
“No number can be divided by zero?” they are told.
“Why?”
“Why?”
“Why?”
“ ...”
I don’t know!
