We look at the division of 863894 by 14 
The aim is to understand the frequency of 14 in 863894.

Advancing to step 1:
14 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 14

On to step 2:
The number 14 fits into 86 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 2 after subtracting 84 from 86.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 14

Let's proceed to step 3:
14 can be fit into 23 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 14 from 23, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 14

Let's proceed to step 4:
When dividing 98 by 14, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 617.0
Subtract 98 from 98 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 14

Step 5:
14 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 6170.0
Subtract 0 from 9 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 14

Let's proceed to step 6:
14 can be fit into 94 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 61706.0
Deduct 84 from 94 and we're left 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 7:
14 can be fit into 100 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 61706.7
If we take 98 away from 100, we end up 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.

On to step 8:
When dividing 20 by 14, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 61706.71
The remainder is 6 after subtracting 14 from 20.
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 9:
14 goes into 60 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 61706.714
Subtracting 56 from 60 leaves us 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.

Going ahead to step 10:
14 can be fit into 40 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 61706.7142
Subtract 28 from 40 to 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.

Let's proceed to step 11:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 61706.71428
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.

On to step 12:
14 goes into 80 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 61706.714285
If we subtract 70 from 80, we 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.

Advancing to step 13:
100 divided by 14 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 61706.7142857
Deduct 98 from 100 and we're left 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.

Advancing to step 14:
The number 14 fits into 20 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 61706.71428571
If we subtract 14 from 20, 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.

After the division, we end up with 61706.71428571 and a remainder of 6e-09.
