What are the required steps to convert base 10 decimal system
number 2 148 016 917 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;
  • 2 148 016 917 ÷ 2 = 1 074 008 458 + 1;
  • 1 074 008 458 ÷ 2 = 537 004 229 + 0;
  • 537 004 229 ÷ 2 = 268 502 114 + 1;
  • 268 502 114 ÷ 2 = 134 251 057 + 0;
  • 134 251 057 ÷ 2 = 67 125 528 + 1;
  • 67 125 528 ÷ 2 = 33 562 764 + 0;
  • 33 562 764 ÷ 2 = 16 781 382 + 0;
  • 16 781 382 ÷ 2 = 8 390 691 + 0;
  • 8 390 691 ÷ 2 = 4 195 345 + 1;
  • 4 195 345 ÷ 2 = 2 097 672 + 1;
  • 2 097 672 ÷ 2 = 1 048 836 + 0;
  • 1 048 836 ÷ 2 = 524 418 + 0;
  • 524 418 ÷ 2 = 262 209 + 0;
  • 262 209 ÷ 2 = 131 104 + 1;
  • 131 104 ÷ 2 = 65 552 + 0;
  • 65 552 ÷ 2 = 32 776 + 0;
  • 32 776 ÷ 2 = 16 388 + 0;
  • 16 388 ÷ 2 = 8 194 + 0;
  • 8 194 ÷ 2 = 4 097 + 0;
  • 4 097 ÷ 2 = 2 048 + 1;
  • 2 048 ÷ 2 = 1 024 + 0;
  • 1 024 ÷ 2 = 512 + 0;
  • 512 ÷ 2 = 256 + 0;
  • 256 ÷ 2 = 128 + 0;
  • 128 ÷ 2 = 64 + 0;
  • 64 ÷ 2 = 32 + 0;
  • 32 ÷ 2 = 16 + 0;
  • 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.

2 148 016 917(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:

2 148 016 917 (base 10) = 1000 0000 0000 1000 0010 0011 0001 0101 (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)
