64439682 ÷ 12 
The aim is to understand the frequency of 12 in 64439682.

Advancing to step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 12

On to step 2:
When dividing 64 by 12, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 4 after subtracting 60 from 64.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

On to step 3:
The number 12 fits into 44 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 36 from 44 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 12

Advancing to step 4:
12 goes into 83 6 times with a remainder of 11.
The next digit of our result is 6. 
Result so far: 536.0
If we take 72 away from 83, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 12

Going ahead to step 5:
12 goes into 119 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 5369.0
If we subtract 108 from 119, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 12

Advancing to step 6:
12 can be fit into 116 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 53699.0
The remainder is 8 after subtracting 108 from 116.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 12

Step 7:
When dividing 88 by 12, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 536997.0
If we take 84 away from 88, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 12

Let's proceed to step 8:
The number 12 fits into 42 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 5369973.0
Subtracting 36 from 42 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.

Let's proceed to step 9:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5369973.5
Subtracting 60 from 60 leaves us 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.

Moving on to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5369973.5
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.

Advancing to step 11:
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: 5369973.5
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.

The final result is 5369973.5 with a remainder of 0.0.
