728297 divided by 12 
The aim is to understand the frequency of 12 in 728297.

Let's proceed to step 1:
When dividing 7 by 12, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 12

Moving on to step 2:
When dividing 72 by 12, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 72 away from 72, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 12

On to step 3:
8 divided by 12 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 60.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 12

Step 4:
82 divided by 12 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 606.0
Subtract 72 from 82 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 12

Advancing to step 5:
If we divide 109 by 12, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 6069.0
Deduct 108 from 109 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 12

Step 6:
When dividing 17 by 12, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 60691.0
Subtracting 12 from 17 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 12, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 60691.4
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
12 goes into 20 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 60691.41
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.

Going ahead to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 60691.416
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.

Step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 60691.4166
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.

In conclusion, the division gives 60691.4166 with a balance of 8e-05.
