We look at the division of 99380 by 12 
The aim is to understand the frequency of 12 in 99380.

Going ahead to step 1:
When dividing 9 by 12, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 12

Advancing to step 2:
The number 12 fits into 99 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 3 after subtracting 96 from 99.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 12

Moving on to step 3:
The number 12 fits into 33 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
The remainder is 9 after subtracting 24 from 33.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 12

Advancing to step 4:
The number 12 fits into 98 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 828.0
Subtracting 96 from 98 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 12

Going ahead to step 5:
When dividing 20 by 12, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 8281.0
Deduct 12 from 20 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.

Step 6:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 8281.6
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.

On to step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 8281.66
Deduct 72 from 80 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.

Our division results in 8281.66 with a remaining 0.008.
