We're dividing 667622 by 9 
The aim is to understand the frequency of 9 in 667622.

Going ahead to step 1:
The number 9 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 9

Let's proceed to step 2:
66 divided by 9 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 63 from 66 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 9

Let's proceed to step 3:
37 divided by 9 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 74.0
The remainder is 1 after subtracting 36 from 37.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 9

Moving on to step 4:
16 divided by 9 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 741.0
If we take 9 away from 16, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 9

Going ahead to step 5:
72 divided by 9 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 7418.0
If we take 72 away from 72, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 9

Advancing to step 6:
2 divided by 9 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 74180.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 74180.2
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 9 fits into 20 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 74180.22
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 74180.22, with a leftover of 0.002.
