306809 ÷ 14 
The aim is to understand the frequency of 14 in 306809.

On to step 1:
When dividing 3 by 14, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 14

Step 2:
14 goes into 30 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 28 from 30 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 14

Moving on to step 3:
14 can be fit into 26 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 14 from 26, we get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 14

Going ahead to step 4:
14 can be fit into 128 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
If we take 126 away from 128, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 14

Going ahead to step 5:
20 divided by 14 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 2191.0
Subtracting 14 from 20 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 14

Let's proceed to step 6:
When dividing 69 by 14, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 21914.0
Subtract 56 from 69 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
The number 14 fits into 130 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 21914.9
If we take 126 away from 130, we end up 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.

Step 8:
14 goes into 40 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 21914.92
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 14, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 21914.928
Deduct 112 from 120 and we're left 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.

Let's proceed to step 10:
80 divided by 14 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 21914.9285
Subtract 70 from 80 to get 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 11:
14 goes into 100 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 21914.92857
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.

Let's proceed to step 12:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 21914.928571
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.

Going ahead to step 13:
When dividing 60 by 14, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 21914.9285714
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.

Step 14:
When dividing 40 by 14, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 21914.92857142
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 21914.92857142, and the remainder is 1.2e-08.
