How to convert a number to a binary number

In the networking IP4 calculations, an IP address is composed of 32 bits, divided into 4 octets: 00000000.00000000.00000000.00000000 The binary numbers available per octet are: 128 - 64 -32 -16-8- 4 -2-1

How to translate a number to a binary number? 192.168.1.0
128 - 64 -32 -16-8- 4 -2-1
192 = 128 + 64 = 11000000
168 = 128 + 32 + 8 = 10101000
1 = 00000001
0 = 00000000
192.168.1.0 = 11000000.10101000.00000001.00000000
