We look at the division of 125513 by 14 
The aim is to understand the frequency of 14 in 125513.

Moving on to step 1:
1 divided by 14 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 14

Step 2:
The number 14 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 14

Let's proceed to step 3:
125 divided by 14 is 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 112 from 125 to get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 14

Let's proceed to step 4:
14 goes into 135 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtract 126 from 135 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 14

On to step 5:
91 divided by 14 is 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 896.0
If we take 84 away from 91, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 14

Step 6:
The number 14 fits into 73 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 8965.0
If we take 70 away from 73, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
14 can be fit into 30 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 8965.2
If we take 28 away from 30, 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.

Moving on to step 8:
20 divided by 14 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 8965.21
Subtracting 14 from 20 leaves us 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.

Step 9:
14 goes into 60 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 8965.214
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.

Let's proceed to step 10:
If we divide 40 by 14, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 8965.2142
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.

Advancing to step 11:
14 goes into 120 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8965.21428
Subtracting 112 from 120 leaves us 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.

Step 12:
If we divide 80 by 14, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 8965.214285
Deduct 70 from 80 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.

Step 13:
14 goes into 100 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 8965.2142857
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.

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: 8965.21428571
Subtract 14 from 20 to 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.

The final outcome is 8965.21428571, with a leftover of 6e-09.
