280653 divided by 12 
The aim is to understand the frequency of 12 in 280653.

On to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 12

Moving on to step 2:
When dividing 28 by 12, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 24 from 28, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 12

Let's proceed to step 3:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 36 from 40 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 12

On to step 4:
46 divided by 12 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 233.0
If we take 36 away from 46, we end up with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 12

Moving on to step 5:
If we divide 105 by 12, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 2338.0
Deduct 96 from 105 and we're left with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 12

Advancing to step 6:
12 can be fit into 93 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 23387.0
If we take 84 away from 93, we end up 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.

Let's proceed to step 7:
12 can be fit into 90 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 23387.7
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.

On to step 8:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 23387.75
If we take 60 away from 60, 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.

Moving on to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23387.75
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.

Going ahead to step 10:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23387.75
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.

In conclusion, the division gives 23387.75 with a balance of 0.0.
