We look at the division of 82312569 by 12 
The aim is to understand the frequency of 12 in 82312569.

On to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 12

Going ahead to step 2:
The number 12 fits into 82 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 72 away from 82, we end up with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 12

Going ahead to step 3:
If we divide 103 by 12, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Deduct 96 from 103 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 12

Moving on to step 4:
71 divided by 12 is 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 685.0
Subtract 60 from 71 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 12

Let's proceed to step 5:
When dividing 112 by 12, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 6859.0
Subtracting 108 from 112 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 12

On to step 6:
When dividing 45 by 12, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 68593.0
Subtracting 36 from 45 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 12

Advancing to step 7:
The number 12 fits into 96 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 685938.0
The remainder is 0 after subtracting 96 from 96.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 12

Moving on to step 8:
The number 12 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 6859380.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
12 can be fit into 90 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 6859380.7
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
When dividing 60 by 12, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6859380.75
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.

Let's proceed to step 11:
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: 6859380.75
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.

Advancing to step 12:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6859380.75
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.

The final result is 6859380.75 with a remainder of 0.0.
