We look at the division of 884978 by 12 
The aim is to understand the frequency of 12 in 884978.

Going ahead to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 12

Step 2:
88 divided by 12 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 84 from 88 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

Moving on to step 3:
12 can be fit into 44 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 36 away from 44, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 12

Going ahead to step 4:
When dividing 89 by 12, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 737.0
Deduct 84 from 89 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 12

Going ahead to step 5:
When dividing 57 by 12, we get 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 7374.0
The remainder is 9 after subtracting 48 from 57.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 12

Let's proceed to step 6:
12 can be fit into 98 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 73748.0
If we subtract 96 from 98, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 73748.1
If we subtract 12 from 20, 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.

Step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 73748.16
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.

Let's proceed to step 9:
80 divided by 12 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 73748.166
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.

After the division, we end up with 73748.166 and a remainder of 0.0008.
