18003 divided by 8 
Let's see how many times 8 fits into 18003.

Let's proceed to step 1:
8 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 8

Going ahead to step 2:
The number 8 fits into 18 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 16 away from 18, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 8

Let's proceed to step 3:
8 goes into 20 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 16 from 20, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 8

Let's proceed to step 4:
If we divide 40 by 8, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 225.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 8

Moving on to step 5:
3 divided by 8 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 2250.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 6:
30 divided by 8 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 2250.3
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 2250.37
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
8 goes into 40 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2250.375
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2250.375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2250.375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 2250.375 and a remainder of 0.0.
