Let's divide 11878080 by 18
We're looking to find how many times 18 goes into 11878080.

Advancing to step 1:
18 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 18

Going ahead to step 2:
The number 18 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 18

Let's proceed to step 3:
118 divided by 18 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 108 from 118 to get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 18

Moving on to step 4:
18 goes into 107 5 times with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
If we subtract 90 from 107, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 18

Let's proceed to step 5:
178 divided by 18 is 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 659.0
The remainder is 16 after subtracting 162 from 178.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 18

Moving on to step 6:
When dividing 160 by 18, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6598.0
Subtract 144 from 160 to get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 18

Step 7:
If we divide 168 by 18, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 65989.0
Subtract 162 from 168 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 18

On to step 8:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 659893.0
Subtracting 54 from 60 leaves us 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.

Moving on to step 9:
If we divide 60 by 18, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 659893.3
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
60 divided by 18 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 659893.33
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 659893.33, with a leftover of 0.006.
