What are the required steps to convert base 10 decimal system
number 4 789 458 866 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;
  • 4 789 458 866 ÷ 2 = 2 394 729 433 + 0;
  • 2 394 729 433 ÷ 2 = 1 197 364 716 + 1;
  • 1 197 364 716 ÷ 2 = 598 682 358 + 0;
  • 598 682 358 ÷ 2 = 299 341 179 + 0;
  • 299 341 179 ÷ 2 = 149 670 589 + 1;
  • 149 670 589 ÷ 2 = 74 835 294 + 1;
  • 74 835 294 ÷ 2 = 37 417 647 + 0;
  • 37 417 647 ÷ 2 = 18 708 823 + 1;
  • 18 708 823 ÷ 2 = 9 354 411 + 1;
  • 9 354 411 ÷ 2 = 4 677 205 + 1;
  • 4 677 205 ÷ 2 = 2 338 602 + 1;
  • 2 338 602 ÷ 2 = 1 169 301 + 0;
  • 1 169 301 ÷ 2 = 584 650 + 1;
  • 584 650 ÷ 2 = 292 325 + 0;
  • 292 325 ÷ 2 = 146 162 + 1;
  • 146 162 ÷ 2 = 73 081 + 0;
  • 73 081 ÷ 2 = 36 540 + 1;
  • 36 540 ÷ 2 = 18 270 + 0;
  • 18 270 ÷ 2 = 9 135 + 0;
  • 9 135 ÷ 2 = 4 567 + 1;
  • 4 567 ÷ 2 = 2 283 + 1;
  • 2 283 ÷ 2 = 1 141 + 1;
  • 1 141 ÷ 2 = 570 + 1;
  • 570 ÷ 2 = 285 + 0;
  • 285 ÷ 2 = 142 + 1;
  • 142 ÷ 2 = 71 + 0;
  • 71 ÷ 2 = 35 + 1;
  • 35 ÷ 2 = 17 + 1;
  • 17 ÷ 2 = 8 + 1;
  • 8 ÷ 2 = 4 + 0;
  • 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.

4 789 458 866(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

4 789 458 866 (base 10) = 1 0001 1101 0111 1001 0101 0111 1011 0010 (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)
