DECIMAL TO BINARY CONVERSION
 Always divide bits by 2
For example 75 (bits)
divide by 2
37 – 1
37 with 1 left over
divide by 2
18 – 1
18 with 1 left over
divide by 2
9–0
9 with 0 left over
divide by 2
4–1
4 with 1 left over
divide by 2
2–0
2 with 0 left over
divide by 2
1–0
1 with 0 left over
divide by 2
0–1
0 with 1 left over
Always work from the bottom across and then up to determine the
number.
The number will be 01001011.

Example of 53 bits:
53
2
26 – 1
2
13 – 0
2
6–1
2
3–0
2
1–1
2
0-1
Starting from the bottom, going across and up the final number is:
0110101 and then add 1 zero to the front to make 8 digits – the number
becomes 00110101
REMEMBER: As there must always be 8 bits, if you have
less than 8 digits, add 0’s in front to make the number up to 8
digits.
