Let's divide 231103 by 18
Let's see how many times 18 fits into 231103.

Moving on to step 1:
If we divide 2 by 18, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 18

Let's proceed to step 2:
23 divided by 18 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 18 away from 23, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 18

Moving on to step 3:
51 divided by 18 is 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 36 away from 51, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 18

On to step 4:
The number 18 fits into 151 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 144 from 151 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 18

On to step 5:
The number 18 fits into 70 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 1283.0
Subtract 54 from 70 to get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 18

Let's proceed to step 6:
If we divide 163 by 18, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 12839.0
The remainder is 1 after subtracting 162 from 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 18 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12839.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 18 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 12839.05
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
18 goes into 100 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 12839.055
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 12839.055, with a leftover of 0.001.
