28905 ÷ 12 
The aim is to understand the frequency of 12 in 28905.

Going ahead to step 1:
12 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 12

On to step 2:
12 can be fit into 28 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 24 from 28, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Moving on to step 3:
12 goes into 49 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 48 away from 49, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 12

On to step 4:
If we divide 10 by 12, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 240.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 12

Advancing to step 5:
105 divided by 12 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 2408.0
Subtracting 96 from 105 leaves us 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.

Step 6:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2408.7
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.

Moving on to step 7:
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: 2408.75
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.

Going ahead to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2408.75
Deduct 0 from 0 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.

Advancing to step 9:
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: 2408.75
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.

After the division, we end up with 2408.75 and a remainder of 0.0.
