We look at the division of 214081 by 12 
The aim is to understand the frequency of 12 in 214081.

Step 1:
2 divided by 12 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Moving on to step 2:
21 divided by 12 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 12 from 21 leaves us with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 12

Step 3:
12 goes into 94 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 10 after subtracting 84 from 94.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 12

Going ahead to step 4:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 178.0
Subtracting 96 from 100 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 12

On to step 5:
12 can be fit into 48 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1784.0
Subtract 48 from 48 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 12

Step 6:
12 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 17840.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17840.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
12 goes into 100 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 17840.08
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 17840.083
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 17840.0833
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 17840.0833, and the remainder is 4e-05.
