We look at the division of 131645 by 14 
The aim is to understand the frequency of 14 in 131645.

On to step 1:
If we divide 1 by 14, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 14

Step 2:
13 divided by 14 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 14

Advancing to step 3:
The number 14 fits into 131 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 126 from 131, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 14

Let's proceed to step 4:
If we divide 56 by 14, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we subtract 56 from 56, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 14

Let's proceed to step 5:
14 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 940.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 14

On to step 6:
14 can be fit into 45 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 9403.0
Subtract 42 from 45 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
14 goes into 30 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 9403.2
Subtracting 28 from 30 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.

Going ahead to step 8:
20 divided by 14 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 9403.21
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.

Moving on to step 9:
60 divided by 14 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 9403.214
If we take 56 away from 60, 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.

Advancing to step 10:
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: 9403.2142
Subtracting 28 from 40 leaves us with 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 11:
120 divided by 14 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 9403.21428
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.

Let's proceed to step 12:
14 goes into 80 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 9403.214285
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.

Let's proceed to step 13:
When dividing 100 by 14, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 9403.2142857
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.

Going ahead to step 14:
If we divide 20 by 14, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 9403.21428571
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.

Our division results in 9403.21428571 with a remaining 6e-09.
