Let's divide 371239 by 14
The aim is to understand the frequency of 14 in 371239.

Let's proceed to step 1:
When dividing 3 by 14, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 14

Moving on to step 2:
The number 14 fits into 37 2 times, leaving a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 28 from 37 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 14

On to step 3:
The number 14 fits into 91 6 times, leaving a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtract 84 from 91 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 14

Let's proceed to step 4:
The number 14 fits into 72 5 times, leaving a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
The remainder is 2 after subtracting 70 from 72.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 14

Moving on to step 5:
23 divided by 14 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 2651.0
The remainder is 9 after subtracting 14 from 23.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 14

Advancing to step 6:
The number 14 fits into 99 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 26517.0
If we take 98 away from 99, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 14, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 26517.0
If we take 0 away from 10, we end up 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 8:
14 goes into 100 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 26517.07
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.

Moving on to step 9:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 26517.071
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.

Moving on to step 10:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 26517.0714
Subtract 56 from 60 to 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.

Going ahead to step 11:
14 can be fit into 40 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 26517.07142
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.

Going ahead to step 12:
The number 14 fits into 120 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 26517.071428
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 13:
If we divide 80 by 14, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 26517.0714285
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.

Advancing to step 14:
100 divided by 14 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 26517.07142857
Subtracting 98 from 100 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.

The final outcome is 26517.07142857, with a leftover of 2e-09.
