What are the required steps to convert base 10 decimal system
number 4 294 943 438 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;
  • 4 294 943 438 ÷ 2 = 2 147 471 719 + 0;
  • 2 147 471 719 ÷ 2 = 1 073 735 859 + 1;
  • 1 073 735 859 ÷ 2 = 536 867 929 + 1;
  • 536 867 929 ÷ 2 = 268 433 964 + 1;
  • 268 433 964 ÷ 2 = 134 216 982 + 0;
  • 134 216 982 ÷ 2 = 67 108 491 + 0;
  • 67 108 491 ÷ 2 = 33 554 245 + 1;
  • 33 554 245 ÷ 2 = 16 777 122 + 1;
  • 16 777 122 ÷ 2 = 8 388 561 + 0;
  • 8 388 561 ÷ 2 = 4 194 280 + 1;
  • 4 194 280 ÷ 2 = 2 097 140 + 0;
  • 2 097 140 ÷ 2 = 1 048 570 + 0;
  • 1 048 570 ÷ 2 = 524 285 + 0;
  • 524 285 ÷ 2 = 262 142 + 1;
  • 262 142 ÷ 2 = 131 071 + 0;
  • 131 071 ÷ 2 = 65 535 + 1;
  • 65 535 ÷ 2 = 32 767 + 1;
  • 32 767 ÷ 2 = 16 383 + 1;
  • 16 383 ÷ 2 = 8 191 + 1;
  • 8 191 ÷ 2 = 4 095 + 1;
  • 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.

4 294 943 438(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

4 294 943 438 (base 10) = 1111 1111 1111 1111 1010 0010 1100 1110 (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)
