We're dividing 943304 by 12 
The aim is to understand the frequency of 12 in 943304.

On to step 1:
12 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 12

Let's proceed to step 2:
When dividing 94 by 12, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 84 from 94 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 12

Going ahead to step 3:
The number 12 fits into 103 8 times, leaving a remainder of 7.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 96 from 103, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 12

Step 4:
12 goes into 73 6 times with a remainder of 1.
The next digit of our result is 6. 
Result so far: 786.0
If we take 72 away from 73, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

Going ahead to step 5:
10 divided by 12 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7860.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 12

Going ahead to step 6:
12 goes into 104 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 78608.0
Deduct 96 from 104 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.

Advancing to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 78608.6
If we take 72 away from 80, we end up 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.

Advancing to step 8:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 78608.66
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 78608.66 with a remaining 0.008.
