What are the required steps to convert base 10 decimal system
number 9 046 935 578 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;

  • 1 130 866 947 ÷ 2 = 565 433 473 + 1;
  • 565 433 473 ÷ 2 = 282 716 736 + 1;
  • 282 716 736 ÷ 2 = 141 358 368 + 0;
  • 141 358 368 ÷ 2 = 70 679 184 + 0;
  • 70 679 184 ÷ 2 = 35 339 592 + 0;
  • 35 339 592 ÷ 2 = 17 669 796 + 0;
  • 17 669 796 ÷ 2 = 8 834 898 + 0;
  • 8 834 898 ÷ 2 = 4 417 449 + 0;
  • 4 417 449 ÷ 2 = 2 208 724 + 1;
  • 2 208 724 ÷ 2 = 1 104 362 + 0;
  • 1 104 362 ÷ 2 = 552 181 + 0;
  • 552 181 ÷ 2 = 276 090 + 1;
  • 276 090 ÷ 2 = 138 045 + 0;
  • 138 045 ÷ 2 = 69 022 + 1;
  • 69 022 ÷ 2 = 34 511 + 0;
  • 34 511 ÷ 2 = 17 255 + 1;
  • 17 255 ÷ 2 = 8 627 + 1;
  • 8 627 ÷ 2 = 4 313 + 1;
  • 4 313 ÷ 2 = 2 156 + 1;
  • 2 156 ÷ 2 = 1 078 + 0;
  • 1 078 ÷ 2 = 539 + 0;
  • 539 ÷ 2 = 269 + 1;
  • 269 ÷ 2 = 134 + 1;
  • 134 ÷ 2 = 67 + 0;
  • 67 ÷ 2 = 33 + 1;
  • 33 ÷ 2 = 16 + 1;
  • 16 ÷ 2 = 8 + 0;
  • 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.

9 046 935 578(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

9 046 935 578 (base 10) = 10 0001 1011 0011 1101 0100 1000 0001 1010 (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)
