Let's divide 71878 by 14
The aim is to understand the frequency of 14 in 71878.

On to step 1:
If we divide 7 by 14, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 14

On to step 2:
If we divide 71 by 14, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
If we take 70 away from 71, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 14

Let's proceed to step 3:
The number 14 fits into 18 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 14 from 18 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 14

Step 4:
The number 14 fits into 47 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 513.0
The remainder is 5 after subtracting 42 from 47.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 14

Going ahead to step 5:
If we divide 58 by 14, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 5134.0
Subtracting 56 from 58 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.

On to step 6:
The number 14 fits into 20 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 5134.1
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.

Advancing to step 7:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 5134.14
Deduct 56 from 60 and we're left 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.

Let's proceed to step 8:
When dividing 40 by 14, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 5134.142
Deduct 28 from 40 and we're left 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.

Advancing to step 9:
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: 5134.1428
If we subtract 112 from 120, we 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.

Moving on to step 10:
14 goes into 80 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5134.14285
Subtract 70 from 80 to 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 11:
The number 14 fits into 100 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 5134.142857
If we subtract 98 from 100, we 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.

Going ahead to step 12:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 5134.1428571
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 13:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 5134.14285714
Subtracting 56 from 60 leaves us 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.

In conclusion, the division gives 5134.14285714 with a balance of 4e-09.
