What are the required steps to convert base 10 decimal system
number 1 157 234 464 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;
  • 1 157 234 464 ÷ 2 = 578 617 232 + 0;
  • 578 617 232 ÷ 2 = 289 308 616 + 0;
  • 289 308 616 ÷ 2 = 144 654 308 + 0;
  • 144 654 308 ÷ 2 = 72 327 154 + 0;
  • 72 327 154 ÷ 2 = 36 163 577 + 0;
  • 36 163 577 ÷ 2 = 18 081 788 + 1;
  • 18 081 788 ÷ 2 = 9 040 894 + 0;
  • 9 040 894 ÷ 2 = 4 520 447 + 0;
  • 4 520 447 ÷ 2 = 2 260 223 + 1;
  • 2 260 223 ÷ 2 = 1 130 111 + 1;
  • 1 130 111 ÷ 2 = 565 055 + 1;
  • 565 055 ÷ 2 = 282 527 + 1;
  • 282 527 ÷ 2 = 141 263 + 1;
  • 141 263 ÷ 2 = 70 631 + 1;
  • 70 631 ÷ 2 = 35 315 + 1;
  • 35 315 ÷ 2 = 17 657 + 1;
  • 17 657 ÷ 2 = 8 828 + 1;
  • 8 828 ÷ 2 = 4 414 + 0;
  • 4 414 ÷ 2 = 2 207 + 0;
  • 2 207 ÷ 2 = 1 103 + 1;
  • 1 103 ÷ 2 = 551 + 1;
  • 551 ÷ 2 = 275 + 1;
  • 275 ÷ 2 = 137 + 1;
  • 137 ÷ 2 = 68 + 1;
  • 68 ÷ 2 = 34 + 0;
  • 34 ÷ 2 = 17 + 0;
  • 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.

1 157 234 464(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

1 157 234 464 (base 10) = 100 0100 1111 1001 1111 1111 0010 0000 (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)
