964988 ÷ 18 
The aim is to understand the frequency of 18 in 964988.

Let's proceed to step 1:
18 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 18

Going ahead to step 2:
If we divide 96 by 18, we get 5 and a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 90 from 96, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 18

On to step 3:
18 goes into 64 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 54 from 64 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 18

Advancing to step 4:
18 can be fit into 109 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 536.0
Deduct 108 from 109 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 18

Let's proceed to step 5:
If we divide 18 by 18, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 5361.0
If we subtract 18 from 18, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 18

Advancing to step 6:
If we divide 8 by 18, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 53610.0
Subtracting 0 from 8 leaves us 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.

Let's proceed to step 7:
18 goes into 80 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 53610.4
The remainder is 8 after subtracting 72 from 80.
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:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 53610.44
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.

The final outcome is 53610.44, with a leftover of 0.008.
