We look at the division of 600776 by 18 
The aim is to understand the frequency of 18 in 600776.

Going ahead to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 18

Step 2:
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: 3.0
Subtract 54 from 60 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 18

Step 3:
When dividing 60 by 18, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 54 from 60, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 18

Going ahead to step 4:
18 can be fit into 67 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 333.0
Subtracting 54 from 67 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 18

Let's proceed to step 5:
When dividing 137 by 18, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 3337.0
If we subtract 126 from 137, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 18

Step 6:
116 divided by 18 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 33376.0
If we subtract 108 from 116, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 divided by 18 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 33376.4
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
If we divide 80 by 18, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 33376.44
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 33376.44, with a leftover of 0.008.
