How to convert the base ten number 378 145 to base two:
- 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.
To convert a base ten unsigned number (written in decimal system) to base two (written in binary), follow the steps below.
- Divide the number repeatedly by 2: keep track of each remainder.
- Stop when you get a quotient that is equal to zero.
- Construct the base 2 representation of the positive number: take all the remainders starting from the bottom of the list constructed above.
- Below you can see the conversion process to base two and the related calculations.
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;
- 378 145 ÷ 2 = 189 072 + 1;
- 189 072 ÷ 2 = 94 536 + 0;
- 94 536 ÷ 2 = 47 268 + 0;
- 47 268 ÷ 2 = 23 634 + 0;
- 23 634 ÷ 2 = 11 817 + 0;
- 11 817 ÷ 2 = 5 908 + 1;
- 5 908 ÷ 2 = 2 954 + 0;
- 2 954 ÷ 2 = 1 477 + 0;
- 1 477 ÷ 2 = 738 + 1;
- 738 ÷ 2 = 369 + 0;
- 369 ÷ 2 = 184 + 1;
- 184 ÷ 2 = 92 + 0;
- 92 ÷ 2 = 46 + 0;
- 46 ÷ 2 = 23 + 0;
- 23 ÷ 2 = 11 + 1;
- 11 ÷ 2 = 5 + 1;
- 5 ÷ 2 = 2 + 1;
- 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.
Number 378 145(10), a positive integer number (with no sign),
converted from decimal system (from base 10)
and written as an unsigned binary (in base 2):
378 145 (base 10) = 101 1100 0101 0010 0001 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
