18475691 ÷ 803 
Let's see how many times 803 fits into 18475691.

On to step 1:
803 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 803

Let's proceed to step 2:
When dividing 18 by 803, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 803

Going ahead to step 3:
803 can be fit into 184 0 times, resulting in a remainder of 184.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 184, we end up with 184.
Take the next digit (7) from the dividend and append it to 184, then repeat: 1847 / 803

Going ahead to step 4:
803 can be fit into 1847 2 times, resulting in a remainder of 241.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1606 away from 1847, we end up with 241.
Include the next digit (5) from the dividend after 241, then repeat: 2415 / 803

On to step 5:
803 goes into 2415 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 6 after subtracting 2409 from 2415.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 803

Step 6:
66 divided by 803 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 230.0
Subtract 0 from 66 to get 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 803

Moving on to step 7:
803 can be fit into 669 0 times, resulting in a remainder of 669.
The number 0 becomes the next digit in our result. 
Result so far: 2300.0
The remainder is 669 after subtracting 0 from 669.
Take the next digit (1) from the dividend and append it to 669, then repeat: 6691 / 803

On to step 8:
803 goes into 6691 8 times with a remainder of 267.
Write down 8 as next digit of the result. 
Result so far: 23008.0
If we take 6424 away from 6691, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 9:
803 goes into 2670 3 times with a remainder of 261.
The next digit of our result is 3. 
Result so far: 23008.3
Subtracting 2409 from 2670 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 10:
803 goes into 2610 3 times with a remainder of 201.
The next digit of our result is 3. 
Result so far: 23008.33
Subtracting 2409 from 2610 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

The final outcome is 23008.33, with a leftover of 0.201.
