666912 divided by 14 
The aim is to understand the frequency of 14 in 666912.

Moving on to step 1:
6 divided by 14 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 14

Advancing to step 2:
14 goes into 66 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 56 from 66 and we're left with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 14

Let's proceed to step 3:
106 divided by 14 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 98 away from 106, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 14

On to step 4:
14 can be fit into 89 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 476.0
If we take 84 away from 89, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 14

Step 5:
14 goes into 51 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 4763.0
Deduct 42 from 51 and we're left with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 14

On to step 6:
14 can be fit into 92 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 47636.0
If we take 84 away from 92, we end up with 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 7:
If we divide 80 by 14, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 47636.5
Subtracting 70 from 80 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 14, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 47636.57
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 14, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 47636.571
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
When dividing 60 by 14, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 47636.5714
Deduct 56 from 60 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.

Advancing to step 11:
40 divided by 14 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 47636.57142
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
120 divided by 14 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 47636.571428
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 14, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 47636.5714285
If we take 70 away from 80, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
14 goes into 100 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 47636.57142857
Subtracting 98 from 100 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 47636.57142857, with a leftover of 2e-09.
