281586 ÷ 12 
The aim is to understand the frequency of 12 in 281586.

Going ahead to step 1:
12 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 12

Moving on to step 2:
The number 12 fits into 28 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 24 from 28, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 12

Advancing to step 3:
If we divide 41 by 12, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 36 from 41 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

Going ahead to step 4:
12 can be fit into 55 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
If we subtract 48 from 55, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 12

Moving on to step 5:
12 can be fit into 78 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 2346.0
Subtract 72 from 78 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 12

Advancing to step 6:
12 can be fit into 66 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 23465.0
If we subtract 60 from 66, we 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 7:
If we divide 60 by 12, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 23465.5
If we subtract 60 from 60, 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.

On to step 8:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 23465.5
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.

Step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23465.5
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.

The final result is 23465.5 with a remainder of 0.0.
