Let's divide 969964 by 18
The aim is to understand the frequency of 18 in 969964.

Going ahead to step 1:
18 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 18

Moving on to step 2:
96 divided by 18 is 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 90 away from 96, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 18

Step 3:
If we divide 69 by 18, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Deduct 54 from 69 and we're left with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 18

Step 4:
If we divide 159 by 18, we get 8 and a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 538.0
If we subtract 144 from 159, we get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 18

On to step 5:
156 divided by 18 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 5388.0
Subtracting 144 from 156 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 18

Let's proceed to step 6:
18 can be fit into 124 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 53886.0
If we subtract 108 from 124, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
The number 18 fits into 160 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 53886.8
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
If we divide 160 by 18, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 53886.88
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 53886.88 with a remainder of 0.016.
