124124 ÷ 12 
The aim is to understand the frequency of 12 in 124124.

Going ahead to step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 12

Going ahead to step 2:
12 can be fit into 12 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 12 from 12 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 12

Let's proceed to step 3:
If we divide 4 by 12, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 12

Going ahead to step 4:
12 goes into 41 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 36 from 41 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 12

Going ahead to step 5:
The number 12 fits into 52 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1034.0
The remainder is 4 after subtracting 48 from 52.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

On to step 6:
When dividing 44 by 12, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 10343.0
Subtract 36 from 44 to 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.

Going ahead to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 10343.6
Subtract 72 from 80 to 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.

Moving on to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 10343.66
If we subtract 72 from 80, 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.

The final result is 10343.66 with a remainder of 0.008.
