The process involves repeated divisions with whole number quotients and remainder Example: Convert 99 base 10 to base 8
Step 1. 8 into 99 goes 12 times with 3 left over Step 2. 8 into 12 goes 1 time with 4 left over Step 3. 8 into 1 goes 0 times with 1 left over Stop when base goes into dividend 0 times
Then line up the leftovers from last to first: 1,4,3
Result 99(base 10) is 143(base 8)
Check: 143(base 8) = 1*8^2 + 4*8^1 + 3*8^0 = 1*64 + 4*8 + 3*1 = 64 + 32 + 3 = 99 (base 10)
