1. Divide the number repeatedly by 2:

Keep track of each remainder.

We stop when we get a quotient that is equal to zero.

  • division = quotient + remainder;
  • 40 299 975 ÷ 2 = 20 149 987 + 1;
  • 20 149 987 ÷ 2 = 10 074 993 + 1;
  • 10 074 993 ÷ 2 = 5 037 496 + 1;
  • 5 037 496 ÷ 2 = 2 518 748 + 0;
  • 2 518 748 ÷ 2 = 1 259 374 + 0;
  • 1 259 374 ÷ 2 = 629 687 + 0;
  • 629 687 ÷ 2 = 314 843 + 1;
  • 314 843 ÷ 2 = 157 421 + 1;
  • 157 421 ÷ 2 = 78 710 + 1;
  • 78 710 ÷ 2 = 39 355 + 0;
  • 39 355 ÷ 2 = 19 677 + 1;
  • 19 677 ÷ 2 = 9 838 + 1;
  • 9 838 ÷ 2 = 4 919 + 0;
  • 4 919 ÷ 2 = 2 459 + 1;
  • 2 459 ÷ 2 = 1 229 + 1;
  • 1 229 ÷ 2 = 614 + 1;
  • 614 ÷ 2 = 307 + 0;
  • 307 ÷ 2 = 153 + 1;
  • 153 ÷ 2 = 76 + 1;
  • 76 ÷ 2 = 38 + 0;
  • 38 ÷ 2 = 19 + 0;
  • 19 ÷ 2 = 9 + 1;
  • 9 ÷ 2 = 4 + 1;
  • 4 ÷ 2 = 2 + 0;
  • 2 ÷ 2 = 1 + 0;
  • 1 ÷ 2 = 0 + 1;

2. Construct the base 2 representation of the positive number:

Take all the remainders starting from the bottom of the list constructed above.


Number 40 299 975(10), a positive integer number (with no sign),
converted from decimal system (from base 10)
and written as an unsigned binary (in base 2):

40 299 975(10) = 10 0110 0110 1110 1101 1100 0111(2)

Spaces were used to group digits: for binary, by 4, for decimal, by 3.

How to convert unsigned integer numbers (positive) from decimal system (base 10) to binary = simply convert from base ten to base two

Follow the steps below to convert a base ten unsigned integer number to base two:

  • 1. Divide repeatedly by 2 the positive integer number that has to be converted to binary, keeping track of each remainder, until we get a QUOTIENT that is equal to ZERO.
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above. Thus, the last remainder of the divisions becomes the first symbol (the leftmost) of the base two number, while the first remainder becomes the last symbol (the rightmost).

Example: convert the positive integer number 55 from decimal system (base ten) to binary code (base two):

  • 1. Divide repeatedly 55 by 2, keeping track of each remainder, until we get a quotient that is equal to zero:
    • division = quotient + remainder;
    • 55 ÷ 2 = 27 + 1;
    • 27 ÷ 2 = 13 + 1;
    • 13 ÷ 2 = 6 + 1;
    • 6 ÷ 2 = 3 + 0;
    • 3 ÷ 2 = 1 + 1;
    • 1 ÷ 2 = 0 + 1;
  • 2. Construct the base 2 representation of the positive integer number, by taking all the remainders starting from the bottom of the list constructed above:
    55(10) = 11 0111(2)
  • Number 5510, positive integer (no sign), converted from decimal system (base 10) to unsigned binary (base 2) = 11 0111(2)
