We look at the division of 382503 by 12 
The aim is to understand the frequency of 12 in 382503.

On to step 1:
12 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 12

Advancing to step 2:
12 goes into 38 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 36 away from 38, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 12

Let's proceed to step 3:
12 goes into 22 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 12 away from 22, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 12

Going ahead to step 4:
105 divided by 12 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 318.0
The remainder is 9 after subtracting 96 from 105.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 12

Advancing to step 5:
The number 12 fits into 90 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 3187.0
If we take 84 away from 90, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 12

Let's proceed to step 6:
When dividing 63 by 12, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 31875.0
Deduct 60 from 63 and we're left 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.

Let's proceed 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: 31875.2
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.

Advancing to step 8:
12 goes into 60 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 31875.25
Deduct 60 from 60 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 9:
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: 31875.25
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.

Let's proceed to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 31875.25
If we subtract 0 from 0, 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.

After the division, we end up with 31875.25 and a remainder of 0.0.
