What are the required steps to convert base 10 decimal system
number 4 293 967 638 to base 2 unsigned binary equivalent?

  • A number written in base ten, or a decimal system number, is a number written using the digits 0 through 9. A number written in base two, or a binary system number, is a number written using only the digits 0 and 1.

1. Divide the number repeatedly by 2:

Keep track of each remainder.

Stop when you get a quotient that is equal to zero.


  • division = quotient + remainder;
  • 4 293 967 638 ÷ 2 = 2 146 983 819 + 0;
  • 2 146 983 819 ÷ 2 = 1 073 491 909 + 1;
  • 1 073 491 909 ÷ 2 = 536 745 954 + 1;
  • 536 745 954 ÷ 2 = 268 372 977 + 0;
  • 268 372 977 ÷ 2 = 134 186 488 + 1;
  • 134 186 488 ÷ 2 = 67 093 244 + 0;
  • 67 093 244 ÷ 2 = 33 546 622 + 0;
  • 33 546 622 ÷ 2 = 16 773 311 + 0;
  • 16 773 311 ÷ 2 = 8 386 655 + 1;
  • 8 386 655 ÷ 2 = 4 193 327 + 1;
  • 4 193 327 ÷ 2 = 2 096 663 + 1;
  • 2 096 663 ÷ 2 = 1 048 331 + 1;
  • 1 048 331 ÷ 2 = 524 165 + 1;
  • 524 165 ÷ 2 = 262 082 + 1;
  • 262 082 ÷ 2 = 131 041 + 0;
  • 131 041 ÷ 2 = 65 520 + 1;
  • 65 520 ÷ 2 = 32 760 + 0;
  • 32 760 ÷ 2 = 16 380 + 0;
  • 16 380 ÷ 2 = 8 190 + 0;
  • 8 190 ÷ 2 = 4 095 + 0;
  • 4 095 ÷ 2 = 2 047 + 1;
  • 2 047 ÷ 2 = 1 023 + 1;
  • 1 023 ÷ 2 = 511 + 1;
  • 511 ÷ 2 = 255 + 1;
  • 255 ÷ 2 = 127 + 1;
  • 127 ÷ 2 = 63 + 1;
  • 63 ÷ 2 = 31 + 1;
  • 31 ÷ 2 = 15 + 1;
  • 15 ÷ 2 = 7 + 1;
  • 7 ÷ 2 = 3 + 1;
  • 3 ÷ 2 = 1 + 1;
  • 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.

4 293 967 638(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

4 293 967 638 (base 10) = 1111 1111 1111 0000 1011 1111 0001 0110 (base 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 10 to base 2

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)
