5951181 divided by 18 
The aim is to understand the frequency of 18 in 5951181.

Moving on to step 1:
18 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 18

On to step 2:
The number 18 fits into 59 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 54 from 59 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 18

On to step 3:
When dividing 55 by 18, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 54 from 55, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 18

On to step 4:
18 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 330.0
Subtracting 0 from 11 leaves us with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 18

Step 5:
18 goes into 111 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 3306.0
If we take 108 away from 111, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 18

Going ahead to step 6:
18 goes into 38 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 33062.0
Subtracting 36 from 38 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 18

Going ahead to step 7:
21 divided by 18 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 330621.0
Deduct 18 from 21 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
18 goes into 30 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 330621.1
If we take 18 away from 30, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 18, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 330621.16
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
18 goes into 120 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 330621.166
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 330621.166, and the remainder is 0.0012.
