Let's divide 228931 by 18
Our goal is to divide 228931 by 18.

Going ahead to step 1:
2 divided by 18 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 18

Moving on to step 2:
22 divided by 18 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 18 from 22 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 18

Going ahead to step 3:
The number 18 fits into 48 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 36 from 48 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 18

On to step 4:
If we divide 129 by 18, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtract 126 from 129 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 18

Moving on to step 5:
If we divide 33 by 18, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1271.0
Subtract 18 from 33 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 18

On to step 6:
When dividing 151 by 18, we get 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 12718.0
Subtracting 144 from 151 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 18, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 12718.3
Deduct 54 from 70 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
If we divide 160 by 18, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 12718.38
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 18, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 12718.388
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 12718.388, with a leftover of 0.0016.
