What are the required steps to convert base 10 decimal system
number 4 294 835 981 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;
  • 4 294 835 981 ÷ 2 = 2 147 417 990 + 1;
  • 2 147 417 990 ÷ 2 = 1 073 708 995 + 0;
  • 1 073 708 995 ÷ 2 = 536 854 497 + 1;
  • 536 854 497 ÷ 2 = 268 427 248 + 1;
  • 268 427 248 ÷ 2 = 134 213 624 + 0;
  • 134 213 624 ÷ 2 = 67 106 812 + 0;
  • 67 106 812 ÷ 2 = 33 553 406 + 0;
  • 33 553 406 ÷ 2 = 16 776 703 + 0;
  • 16 776 703 ÷ 2 = 8 388 351 + 1;
  • 8 388 351 ÷ 2 = 4 194 175 + 1;
  • 4 194 175 ÷ 2 = 2 097 087 + 1;
  • 2 097 087 ÷ 2 = 1 048 543 + 1;
  • 1 048 543 ÷ 2 = 524 271 + 1;
  • 524 271 ÷ 2 = 262 135 + 1;
  • 262 135 ÷ 2 = 131 067 + 1;
  • 131 067 ÷ 2 = 65 533 + 1;
  • 65 533 ÷ 2 = 32 766 + 1;
  • 32 766 ÷ 2 = 16 383 + 0;
  • 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.

4 294 835 981(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

4 294 835 981 (base 10) = 1111 1111 1111 1101 1111 1111 0000 1101 (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)
