18497102 ÷ 803 
Let's see how many times 803 fits into 18497102.

Step 1:
803 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 803

Moving on to step 2:
When dividing 18 by 803, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 803

Let's proceed to step 3:
184 divided by 803 is 0 with a remainder of 184.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 184 leaves us with 184.
Take the next digit (9) from the dividend and append it to 184, then repeat: 1849 / 803

Let's proceed to step 4:
If we divide 1849 by 803, we get 2 and a remainder of 243.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1606 from 1849 to get 243.
Append the next digit (7) from the dividend to 243 and continue with: 2437 / 803

Going ahead to step 5:
803 can be fit into 2437 3 times, resulting in a remainder of 28.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 2409 from 2437 leaves us with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 803

Going ahead to step 6:
The number 803 fits into 281 0 times, leaving a remainder of 281.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
Subtracting 0 from 281 leaves us with 281.
Append the next digit (0) from the dividend to 281 and continue with: 2810 / 803

Let's proceed to step 7:
803 can be fit into 2810 3 times, resulting in a remainder of 401.
The next digit of our result is 3. 
Result so far: 2303.0
Subtracting 2409 from 2810 leaves us with 401.
Grab the next digit (2) from the dividend, add it to 401, then carry on: 4012 / 803

Step 8:
803 goes into 4012 4 times with a remainder of 800.
Put 4 as the next digit of the answer. 
Result so far: 23034.0
Deduct 3212 from 4012 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 9:
If we divide 8000 by 803, we get 9 and a remainder of 773.
The next digit of our result is 9. 
Result so far: 23034.9
If we subtract 7227 from 8000, we get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

On to step 10:
803 can be fit into 7730 9 times, resulting in a remainder of 503.
Use 9 as the next digit of our solution. 
Result so far: 23034.99
Subtract 7227 from 7730 to get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

After the division, we end up with 23034.99 and a remainder of 0.503.
