52529 ÷ 14 
The aim is to understand the frequency of 14 in 52529.

Step 1:
If we divide 5 by 14, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 14

Going ahead to step 2:
When dividing 52 by 14, we get 3 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.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 14

Advancing to step 3:
When dividing 105 by 14, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 98 away from 105, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 14

Advancing to step 4:
If we divide 72 by 14, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 375.0
Deduct 70 from 72 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 14

On to step 5:
29 divided by 14 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 3752.0
Subtracting 28 from 29 leaves us 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 6:
14 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3752.0
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.

Advancing to step 7:
14 can be fit into 100 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 3752.07
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 8:
20 divided by 14 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 3752.071
If we subtract 14 from 20, we get 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 9:
When dividing 60 by 14, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 3752.0714
If we take 56 away from 60, 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 10:
When dividing 40 by 14, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 3752.07142
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.

Advancing to step 11:
120 divided by 14 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3752.071428
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.

Advancing to step 12:
14 can be fit into 80 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3752.0714285
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 13:
When dividing 100 by 14, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 3752.07142857
The remainder is 2 after subtracting 98 from 100.
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 result is 3752.07142857 with a remainder of 2e-09.
