Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 225

Step 3:
411 divided by 225 is 1 with a remainder of 186.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 186 after subtracting 225 from 411.

The remainder is 199 after subtracting 1350 from 1549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 9:
225 can be fit into 1990 8 times, resulting in a remainder of 190.
Put 8 as the next digit of the answer. 
Result so far: 182956.8
Subtract 1800 from 1990 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
If we divide 1900 by 225, we get 8 and a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 182956.88
Deduct 1800 from 1900 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 182956.88 with a remaining 0.1.
