We're dividing 18854151 by 663 
We want to divide 18854151 by 663.

Going ahead to step 1:
663 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 663

Step 2:
When dividing 18 by 663, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 663

Step 3:
663 can be fit into 188 0 times, resulting in a remainder of 188.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 188 leaves us with 188.
Append the next digit (5) from the dividend to 188 and continue with: 1885 / 663

Let's proceed to step 4:
663 can be fit into 1885 2 times, resulting in a remainder of 559.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1326 away from 1885, we end up with 559.
Fetch the next digit (4) from the dividend, attach it to 559 and continue: 5594 / 663

Step 5:
5594 divided by 663 is 8 with a remainder of 290.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 5304 from 5594 to get 290.
Include the next digit (1) from the dividend after 290, then repeat: 2901 / 663

On to step 6:
The number 663 fits into 2901 4 times, leaving a remainder of 249.
The next digit of our result is 4. 
Result so far: 284.0
If we subtract 2652 from 2901, we get 249.
Grab the next digit (5) from the dividend, add it to 249, then carry on: 2495 / 663

Step 7:
If we divide 2495 by 663, we get 3 and a remainder of 506.
Use 3 as the next digit of our solution. 
Result so far: 2843.0
Subtract 1989 from 2495 to get 506.
Include the next digit (1) from the dividend after 506, then repeat: 5061 / 663

Let's proceed to step 8:
663 goes into 5061 7 times with a remainder of 420.
Write down 7 as next digit of the result. 
Result so far: 28437.0
Subtracting 4641 from 5061 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 9:
663 can be fit into 4200 6 times, resulting in a remainder of 222.
Use 6 as the next digit of our solution. 
Result so far: 28437.6
If we take 3978 away from 4200, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 10:
663 goes into 2220 3 times with a remainder of 231.
The next digit of our result is 3. 
Result so far: 28437.63
Subtract 1989 from 2220 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 11:
When dividing 2310 by 663, we get 3 with a remainder of 321.
Use 3 as the next digit of our solution. 
Result so far: 28437.633
Subtract 1989 from 2310 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

After the division, we end up with 28437.633 and a remainder of 0.0321.
