We're dividing 215118 by 9 
The aim is to understand the frequency of 9 in 215118.

On to step 1:
The number 9 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 9

Step 2:
21 divided by 9 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 18 from 21 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 9

Let's proceed to step 3:
When dividing 35 by 9, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 27 from 35 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 9

Advancing to step 4:
9 can be fit into 81 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 239.0
Subtracting 81 from 81 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 9

Step 5:
9 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 2390.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 9

Let's proceed to step 6:
When dividing 18 by 9, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 23902.0
Deduct 18 from 18 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
0 divided by 9 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23902.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 9, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23902.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 23902.0, with a leftover of 0.0.
