We look at the division of 5270810 by 14 
The aim is to understand the frequency of 14 in 5270810.

Going ahead to step 1:
If we divide 5 by 14, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 14

Step 2:
14 goes into 52 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 42 from 52 to get 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 14

Let's proceed to step 3:
If we divide 107 by 14, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 98 from 107 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 14

Step 4:
14 goes into 90 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 376.0
Subtract 84 from 90 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 14

On to step 5:
14 goes into 68 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 3764.0
The remainder is 12 after subtracting 56 from 68.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 14

Step 6:
14 goes into 121 8 times with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 37648.0
Deduct 112 from 121 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 14

Going ahead to step 7:
When dividing 90 by 14, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 376486.0
Deduct 84 from 90 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.

Let's proceed to step 8:
60 divided by 14 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 376486.4
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.

Advancing to step 9:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 376486.42
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.

Advancing to step 10:
If we divide 120 by 14, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 376486.428
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 11:
14 goes into 80 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 376486.4285
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.

On to step 12:
If we divide 100 by 14, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 376486.42857
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.

Let's proceed to step 13:
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: 376486.428571
If we take 14 away from 20, we end up 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.

Going ahead to step 14:
The number 14 fits into 60 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 376486.4285714
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.

Advancing to step 15:
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: 376486.42857142
If we take 28 away from 40, we end up 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.

After the division, we end up with 376486.42857142 and a remainder of 1.2e-08.
