4122 ÷ 18 
Let's see how many times 18 fits into 4122.

Step 1:
18 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 18

On to step 2:
18 can be fit into 41 2 times, resulting in a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 36 from 41, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 18

Going ahead to step 3:
When dividing 52 by 18, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 36 away from 52, we end up with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 18

Advancing to step 4:
18 can be fit into 162 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
If we subtract 162 from 162, we get 0.
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 5:
The number 18 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 229.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 6:
18 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 229.0
Subtracting 0 from 0 leaves us 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.

The final outcome is 229.0, with a leftover of 0.0.
