If you want to check the divisibility of any number (in this case 25110) from any particular number(in this case 45)

then break the divisor into factors and check its divisibilty with that dividend.

Factors of 45=3*3*5

Check the divisibilty of the dividend from this small number

for checking a number divisibilty from 3 just add the digits of the dividend and check if the sum is divisible by 3,

now the other factor is 5 for checking a number’s divisibilty by 5 just check its unit digit number if that unit digit is 5 or 0 then it is divisibilty by 5 otherwise not

so in this case 25110 the sum of digits is 2+5+1+1+0

and the unit digit is 0 therefore this number is divisible by 45
