We look at the division of 178380 by 12 
The aim is to understand the frequency of 12 in 178380.

Let's proceed to step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 12

Advancing to step 2:
When dividing 17 by 12, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 12 from 17 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

Going ahead to step 3:
12 goes into 58 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 48 away from 58, we end up with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 12

Going ahead to step 4:
When dividing 103 by 12, we get 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 148.0
If we take 96 away from 103, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 12

Going ahead to step 5:
The number 12 fits into 78 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 1486.0
Deduct 72 from 78 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 12

On to step 6:
When dividing 60 by 12, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 14865.0
If we subtract 60 from 60, we get 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 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14865.0
If we take 0 away from 0, we end up 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.

Let's proceed to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14865.0
Subtract 0 from 0 to get 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 14865.0, and the remainder is 0.0.
