We look at the division of 157643 by 14 
The aim is to understand the frequency of 14 in 157643.

On to step 1:
The number 14 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 14

Going ahead to step 2:
15 divided by 14 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 14 from 15 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 14

On to step 3:
14 goes into 17 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 14 from 17 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 14

Let's proceed to step 4:
If we divide 36 by 14, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
The remainder is 8 after subtracting 28 from 36.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 14

Let's proceed to step 5:
14 goes into 84 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1126.0
Subtracting 84 from 84 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 14

Going ahead to step 6:
14 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 11260.0
Subtract 0 from 3 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.

Advancing to step 7:
If we divide 30 by 14, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 11260.2
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.

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: 11260.21
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.

Moving on to step 9:
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: 11260.214
If we subtract 56 from 60, we get 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 10:
The number 14 fits into 40 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 11260.2142
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.

Let's proceed to step 11:
If we divide 120 by 14, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 11260.21428
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
If we divide 80 by 14, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11260.214285
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.

Going ahead to step 13:
14 goes into 100 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 11260.2142857
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.

On to step 14:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11260.21428571
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.

The final result is 11260.21428571 with a remainder of 6e-09.
