We look at the division of 18618424 by 12 
Our goal is to divide 18618424 by 12.

Let's proceed to step 1:
12 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 12

On to step 2:
12 can be fit into 18 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 12 away from 18, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

On to step 3:
If we divide 66 by 12, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 60 from 66 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 12

Let's proceed to step 4:
61 divided by 12 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
If we take 60 away from 61, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 12

On to step 5:
18 divided by 12 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1551.0
The remainder is 6 after subtracting 12 from 18.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

Moving on to step 6:
12 goes into 64 5 times with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 15515.0
Subtracting 60 from 64 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Moving on to step 7:
When dividing 42 by 12, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 155153.0
Subtract 36 from 42 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 12

On to step 8:
When dividing 64 by 12, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 1551535.0
If we subtract 60 from 64, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 1551535.3
If we take 36 away from 40, we end up 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.

Advancing to step 10:
12 goes into 40 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 1551535.33
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 1551535.33 with a balance of 0.004.
