What are the required steps to convert base 10 decimal system
number 4 286 578 258 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;
  • 4 286 578 258 ÷ 2 = 2 143 289 129 + 0;
  • 2 143 289 129 ÷ 2 = 1 071 644 564 + 1;
  • 1 071 644 564 ÷ 2 = 535 822 282 + 0;
  • 535 822 282 ÷ 2 = 267 911 141 + 0;
  • 267 911 141 ÷ 2 = 133 955 570 + 1;
  • 133 955 570 ÷ 2 = 66 977 785 + 0;
  • 66 977 785 ÷ 2 = 33 488 892 + 1;
  • 33 488 892 ÷ 2 = 16 744 446 + 0;
  • 16 744 446 ÷ 2 = 8 372 223 + 0;
  • 8 372 223 ÷ 2 = 4 186 111 + 1;
  • 4 186 111 ÷ 2 = 2 093 055 + 1;
  • 2 093 055 ÷ 2 = 1 046 527 + 1;
  • 1 046 527 ÷ 2 = 523 263 + 1;
  • 523 263 ÷ 2 = 261 631 + 1;
  • 261 631 ÷ 2 = 130 815 + 1;
  • 130 815 ÷ 2 = 65 407 + 1;
  • 65 407 ÷ 2 = 32 703 + 1;
  • 32 703 ÷ 2 = 16 351 + 1;
  • 16 351 ÷ 2 = 8 175 + 1;
  • 8 175 ÷ 2 = 4 087 + 1;
  • 4 087 ÷ 2 = 2 043 + 1;
  • 2 043 ÷ 2 = 1 021 + 1;
  • 1 021 ÷ 2 = 510 + 1;
  • 510 ÷ 2 = 255 + 0;
  • 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.

4 286 578 258(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

4 286 578 258 (base 10) = 1111 1111 0111 1111 1111 1110 0101 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)
