Align the two numbers as you would in decimal subtraction.
Append leading zeros if necessary to represent both numbers with the same number of digits
Apply two's complement to the second term
Add the complemented number to the first term.
The sum in the previous step should have one more digit than you started with.
An easy way is to convert them to decimal, subtract, then convert the answer back to binary.
1110-111 in binary = 999
You must first convert them to a common base. For example, convert all to binary.
The number 65 in binary is 1000001. The digits in a binary number are exponents of 2 rather than 10, so that for a seven digit number in binary, the digit places represent 64, 32, 16, 8, 4, 2, 1 instead of increasing values of 10. 1000001 = 64+0+0+0+0+0+1 = 65 To create a binary number, use places for all exponent values of 2 that are less than your number. Subtract the largest digit (here 64) and see if each successive smaller digit can be subtracted. If it can, enter a 1 value and subtract again. Here, the remainder is 1, so write 0 values in the digit places for 32, 16, 8, 4, and 2, and then the final 1 = 1.
The distributive property of subtraction states that when subtracting a number from the sum of two other numbers, you can subtract the same number from each of the two numbers separately, and then subtract the two results. This can be represented as: a - (b + c) = (a - b) + (a - c).

There are a few rules to perform arithmetic operations in binary numbers. According to those rules you can add or subtract binary numbers. There are only two arithmetic operations used in binary numbers, they are addition and subtraction.
10011 binary or 19 in decimal.
Operations, or more precisely, binary mathematical operations
If the number is less than 1/2 put a 0 in the first place to the right of the binary point; if it is greater than or equal to 1/2 (0.5) put a 1 there and subtract 1/2 from the original number. _ _ 0.0 _ _0.313 remainingIf the remainder is less than 1/4 put a 0 in the 2nd place to the right of the binary point; if it is greater than or equal to 1/4 (0.25) put a 1 there and subtract 1/4 from the leftover number. _ _ 0.01 _ _0.063 remainingIf the remainder is less than 1/8 put a 0 in the 3rd place to the right of the binary point; if it is greater than or equal to 1/8 (0.125) put a 1 there and subtract 1/8 from the leftover number. _ _ 0.010 _ _0.063 remainingIf the remainder is less than 1/16 (0.0625) put a 0 in the 4th place to the right of the binary point; if it is greater than or equal to 1/16 put a 1 there and subtract 1/16 from the leftover number. _ _ 0.0101 _ _0.0005 remainingIf the remainder is less than 1/32 (0.03125) put a 0 in the 5th place to the right of the binary point; if it is greater than or equal to 1/32 put a 1 there and subtract 1/32 from the leftover number. _ _ 0.01010 _ _0.0005 remaining... and so on until you have no remainder or a repeating pattern.

You do it exactly like decimal subtraction, and when needed you borrow from the next higher place digit, however remember you borrow 2 everytime and not 10. Some people convert the two binary numbers into decimal, do the subtraction and then convert the result back to binary. Following is an example of binary subtraction. 1001 0110 ____ 0011 ____ I started explaining the borrowing process in words but it gets confusing. Please relate it to the borrowing process in decimal.
The number 60 in binary is 111100. The digits in a binary number are exponents of 2 rather than 10, so that for a six digit number in binary, the digit places represent 32, 16, 8, 4, 2, 1 instead of increasing values of 10. 111100 = 32+16+8+4+0+0 = 60 To create a binary number, use places for all exponent values of 2 that are less than your number. Subtract the largest digit (here 32) and see if each successive smaller digit can be subtracted. If it can, enter a 1 value and subtract again. Here, the remainder is 28, so there is a 16, leaving 12, an 8, leaving 4, and a 4, leaving 0. Write 0 values in the digit places for 2 and 1
