We're dividing 75188 by 19 
The aim is to understand the frequency of 19 in 75188.

On to step 1:
19 goes into 7 0 times with 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.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 19

Advancing to step 2:
When dividing 75 by 19, we get 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 57 away from 75, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 19

On to step 3:
19 goes into 181 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 171 from 181 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 19

Let's proceed to step 4:
19 can be fit into 108 5 times, resulting in a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 395.0
Deduct 95 from 108 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 19

Step 5:
19 goes into 138 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 3957.0
Deduct 133 from 138 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 6:
If we divide 50 by 19, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 3957.2
If we subtract 38 from 50, 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.

Going ahead to step 7:
19 can be fit into 120 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3957.26
If we subtract 114 from 120, 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.

Let's proceed to step 8:
60 divided by 19 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 3957.263
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
When dividing 30 by 19, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 3957.2631
If we take 19 away from 30, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
When dividing 110 by 19, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3957.26315
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 3957.263157
If we subtract 133 from 150, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
When dividing 170 by 19, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 3957.2631578
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
When dividing 180 by 19, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 3957.26315789
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 3957.26315789 and a remainder of 9e-09.
