We look at the division of 879015 by 12 
The aim is to understand the frequency of 12 in 879015.

Moving on to step 1:
8 divided by 12 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Step 2:
If we divide 87 by 12, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 84 from 87, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 12

Moving on to step 3:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 73.0
Subtracting 36 from 39 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Advancing to step 4:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 732.0
Subtract 24 from 30 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 12

Moving on to step 5:
When dividing 61 by 12, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 7325.0
If we take 60 away from 61, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 12

Going ahead to step 6:
12 can be fit into 15 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 73251.0
Subtracting 12 from 15 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 12, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 73251.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 73251.25
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 73251.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 73251.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 73251.25, and the remainder is 0.0.
