We divide 55371120 by 18
The aim is to understand the frequency of 18 in 55371120.

Advancing to step 1:
18 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 18

Going ahead to step 2:
55 divided by 18 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 1 after subtracting 54 from 55.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 18

Going ahead to step 3:
18 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 18

Step 4:
If we divide 137 by 18, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 307.0
The remainder is 11 after subtracting 126 from 137.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 18

Let's proceed to step 5:
18 goes into 111 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 3076.0
Subtract 108 from 111 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 18

Let's proceed to step 6:
18 can be fit into 31 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 30761.0
If we take 18 away from 31, we end up with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 18

On to step 7:
132 divided by 18 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 307617.0
Deduct 126 from 132 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 18

Advancing to step 8:
18 can be fit into 60 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3076173.0
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 18 fits into 60 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 3076173.3
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.

Let's proceed to step 10:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3076173.33
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.

Our division results in 3076173.33 with a remaining 0.006.
