Let's divide 525276 by 12
The aim is to understand the frequency of 12 in 525276.

Step 1:
12 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 12

Moving on to step 2:
When dividing 52 by 12, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 48 from 52, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

Going ahead to step 3:
If we divide 45 by 12, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 36 from 45, we get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 12

Going ahead to step 4:
12 can be fit into 92 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 437.0
Subtract 84 from 92 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Moving on to step 5:
The number 12 fits into 87 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4377.0
Subtract 84 from 87 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 12

Let's proceed to step 6:
When dividing 36 by 12, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 43773.0
Subtract 36 from 36 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.

Step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43773.0
Deduct 0 from 0 and we're left 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.

Going ahead to step 8:
12 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43773.0
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.

Our division results in 43773.0 with a remaining 0.0.
