Let's divide 978968 by 18
The aim is to understand the frequency of 18 in 978968.

Let's proceed to step 1:
18 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 18

Advancing to step 2:
The number 18 fits into 97 5 times, leaving a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 90 from 97 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 18

Step 3:
When dividing 78 by 18, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 54.0
Subtract 72 from 78 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 18

Step 4:
18 can be fit into 69 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 543.0
The remainder is 15 after subtracting 54 from 69.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 18

Moving on to step 5:
When dividing 156 by 18, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 5438.0
If we take 144 away from 156, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 18

Advancing to step 6:
18 can be fit into 128 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 54387.0
Subtract 126 from 128 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 54387.1
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 18, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 54387.11
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 54387.11 and a remainder of 0.002.
