We look at the division of 18582870 by 663 
Let's see how many times 663 fits into 18582870.

Advancing to step 1:
1 divided by 663 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 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.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 663

Let's proceed to step 3:
663 can be fit into 185 0 times, resulting in a remainder of 185.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 185 leaves us with 185.
Take the next digit (8) from the dividend and append it to 185, then repeat: 1858 / 663

Advancing to step 4:
663 can be fit into 1858 2 times, resulting in a remainder of 532.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1326 from 1858 to get 532.
Append the next digit (2) from the dividend to 532 and continue with: 5322 / 663

On to step 5:
If we divide 5322 by 663, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 5304 from 5322 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 663

Advancing to step 6:
663 goes into 188 0 times with a remainder of 188.
Write down 0 as next digit of the result. 
Result so far: 280.0
Deduct 0 from 188 and we're left with 188.
Grab the next digit (7) from the dividend, add it to 188, then carry on: 1887 / 663

Advancing to step 7:
663 can be fit into 1887 2 times, resulting in a remainder of 561.
The number 2 becomes the next digit in our result. 
Result so far: 2802.0
Deduct 1326 from 1887 and we're left with 561.
Append the next digit (0) from the dividend to 561 and continue with: 5610 / 663

Advancing to step 8:
5610 divided by 663 is 8 with a remainder of 306.
The next digit of our result is 8. 
Result so far: 28028.0
Subtracting 5304 from 5610 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 9:
If we divide 3060 by 663, we get 4 and a remainder of 408.
The number 4 becomes the next digit in our result. 
Result so far: 28028.4
If we take 2652 away from 3060, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 10:
663 can be fit into 4080 6 times, resulting in a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 28028.46
The remainder is 102 after subtracting 3978 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 11:
If we divide 1020 by 663, we get 1 and a remainder of 357.
The next digit of our result is 1. 
Result so far: 28028.461
Subtract 663 from 1020 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 12:
3570 divided by 663 is 5 with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 28028.4615
The remainder is 255 after subtracting 3315 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 13:
663 can be fit into 2550 3 times, resulting in a remainder of 561.
The next digit of our result is 3. 
Result so far: 28028.46153
If we take 1989 away from 2550, we end up with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Advancing to step 14:
When dividing 5610 by 663, we get 8 with a remainder of 306.
The next digit of our result is 8. 
Result so far: 28028.461538
The remainder is 306 after subtracting 5304 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 15:
663 can be fit into 3060 4 times, resulting in a remainder of 408.
Write down 4 as next digit of the result. 
Result so far: 28028.4615384
Subtracting 2652 from 3060 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 16:
663 goes into 4080 6 times with a remainder of 102.
The next digit of our result is 6. 
Result so far: 28028.46153846
If we take 3978 away from 4080, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 28028.46153846, with a leftover of 1.02e-07.
