From the problem, we have :
Divide the first digit which is 5 by 3 and take the whole number.
That will be :
5/3 = 1.667..
So it is 1.
Write 1 above the digit 5.
Multiply 1 by 3 and subtract from 5.
That will be :
1 x 3 = 3
5 - 3 = 2
Write 3 below the digit 5 and perform subtraction.
Bring down the next digit which is 8.
Divide 28 by 3 and take the whole number.
That will be :
28/3 = 9.33..
So it is 9
Write 9 above the digit 8.
Multiply 9 by 3 and write the result below 28.
That will be :
9 x 3 = 27
Divide 15 by 3.
That will be :
15/3 = 5
Write 5 above the digit 5.
Then perform subtraction, that will be :
28 - 27 = 1
Bring down the next digit which is 5.
Multipl 5 by 3. That will be :
5 x 3 = 15
Write 15 below 15 and perform subtraction.
15 - 15 = 0
Since the result is 0, there is no remainder.
ANSWER :
The quotient is 195
