212192 ÷ 9 
The aim is to understand the frequency of 9 in 212192.

Advancing to step 1:
When dividing 2 by 9, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 9

Moving on to step 2:
If we divide 21 by 9, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 18 from 21 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 9

Going ahead to step 3:
9 can be fit into 32 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 27 away from 32, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 9

Moving on to step 4:
51 divided by 9 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 235.0
If we subtract 45 from 51, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 9

Moving on to step 5:
If we divide 69 by 9, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 2357.0
Deduct 63 from 69 and we're left with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 9

Let's proceed to step 6:
When dividing 62 by 9, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 23576.0
Deduct 54 from 62 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.

Let's proceed to step 7:
80 divided by 9 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 23576.8
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.

Let's proceed to step 8:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 23576.88
Subtract 72 from 80 to 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.

Our division results in 23576.88 with a remaining 0.008.
