We look at the division of 31615 by 14 
The aim is to understand the frequency of 14 in 31615.

Step 1:
14 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 14

Let's proceed to step 2:
14 goes into 31 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 28 from 31, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 14

Advancing to step 3:
If we divide 36 by 14, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 8 after subtracting 28 from 36.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 14

Moving on to step 4:
If we divide 81 by 14, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 225.0
Subtract 70 from 81 to get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 14

Moving on to step 5:
115 divided by 14 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 2258.0
If we subtract 112 from 115, we 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 6:
14 goes into 30 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2258.2
Subtract 28 from 30 to 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.

Moving on to step 7:
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: 2258.21
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.

Let's proceed to step 8:
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: 2258.214
The remainder is 4 after subtracting 56 from 60.
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 9:
The number 14 fits into 40 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2258.2142
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.

Going ahead to step 10:
14 goes into 120 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 2258.21428
Subtract 112 from 120 to get 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 11:
The number 14 fits into 80 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2258.214285
The remainder is 10 after subtracting 70 from 80.
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 12:
14 goes into 100 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 2258.2142857
The remainder is 2 after subtracting 98 from 100.
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 13:
The number 14 fits into 20 1 times, leaving a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 2258.21428571
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.

The quotient of the division is 2258.21428571, and the remainder is 6e-09.
