We're dividing 252038 by 12 
The aim is to understand the frequency of 12 in 252038.

Moving on to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 12

Let's proceed to step 2:
If we divide 25 by 12, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 24 from 25 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 12

Going ahead to step 3:
When dividing 12 by 12, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 0 after subtracting 12 from 12.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 12

Going ahead to step 4:
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: 210.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 12

Moving on to step 5:
When dividing 3 by 12, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 2100.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 12

Going ahead to step 6:
The number 12 fits into 38 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 21003.0
Subtract 36 from 38 to 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.

On to step 7:
12 goes into 20 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 21003.1
Subtract 12 from 20 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.

On to step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 21003.16
Subtracting 72 from 80 leaves us 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.

Going ahead to step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 21003.166
Subtracting 72 from 80 leaves us 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.

The quotient of the division is 21003.166, and the remainder is 0.0008.
