To make a long divition you write the number as follow:
1. As the first digit of the divident is not divisible in the divisor, you take the firt two digits of the divident and divide into the divisor.
How many times does 8 fit in 41: 5
You write the 5 in the quotient:
2. You multiply 5 by 8 (5x8=40) and write the result under the first two digirts of the divident, then you make a substraction:
3. Bring down the next digit of the divident:
4. Divide 16 into 8.
How many times does 8 fit in 16: 2
Repeat the steps 1 and 2:
You finally get:
