How many zeros are in all natural numbers from 1 to 2019?

Problem :



How many zeros are in all natural numbers from 1 to 2019 ?



My attempt :



From 1 to 100 we have 11 zeros




Now from 101 to 110 we have 10 zeros



So from 20 zeros



Moreover from 101 to 1000 we have 201 zeros



But its very tried I need simple method to calculated this zeros
