We're dividing 75389930 by 14 
The aim is to understand the frequency of 14 in 75389930.

Moving on to step 1:
14 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 14

Advancing to step 2:
When dividing 75 by 14, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 70 from 75 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 14

Let's proceed to step 3:
If we divide 53 by 14, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 53.0
Subtracting 42 from 53 leaves us with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 14

Going ahead to step 4:
The number 14 fits into 118 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 538.0
Subtract 112 from 118 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 14

Let's proceed to step 5:
When dividing 69 by 14, we get 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 5384.0
If we take 56 away from 69, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 14

On to step 6:
139 divided by 14 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 53849.0
Subtract 126 from 139 to get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 14

Moving on to step 7:
14 goes into 133 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 538499.0
The remainder is 7 after subtracting 126 from 133.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 14

Let's proceed to step 8:
If we divide 70 by 14, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 5384995.0
Subtracting 70 from 70 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
14 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5384995.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
When dividing 0 by 14, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5384995.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 5384995.0 with a remainder of 0.0.
