531663 divided by 14 
The aim is to understand the frequency of 14 in 531663.

Going ahead to step 1:
The number 14 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 14

Going ahead to step 2:
14 can be fit into 53 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 42 from 53 leaves us with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 14

On to step 3:
The number 14 fits into 111 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we subtract 98 from 111, we get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 14

Advancing to step 4:
14 can be fit into 136 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 379.0
Deduct 126 from 136 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 14

Let's proceed to step 5:
The number 14 fits into 106 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 3797.0
Deduct 98 from 106 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 14

Going ahead to step 6:
When dividing 83 by 14, we get 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 37975.0
If we subtract 70 from 83, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
14 can be fit into 130 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 37975.9
If we take 126 away from 130, we end up 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.

Step 8:
40 divided by 14 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 37975.92
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.

Moving on to step 9:
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: 37975.928
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.

Let's proceed to step 10:
The number 14 fits into 80 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 37975.9285
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.

Let's proceed to step 11:
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: 37975.92857
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.

Going ahead to step 12:
20 divided by 14 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 37975.928571
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.

On to step 13:
14 goes into 60 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 37975.9285714
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.

Let's proceed to step 14:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 37975.92857142
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.

After the division, we end up with 37975.92857142 and a remainder of 1.2e-08.
