We're dividing 90369 by 19 
The aim is to understand the frequency of 19 in 90369.

Moving on to step 1:
When dividing 9 by 19, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 19

Advancing to step 2:
When dividing 90 by 19, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 76 from 90 leaves us with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 19

Going ahead to step 3:
143 divided by 19 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 133 away from 143, we end up with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 19

Moving on to step 4:
19 can be fit into 106 5 times, resulting in a remainder of 11.
The next digit of our result is 5. 
Result so far: 475.0
Subtract 95 from 106 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 19

On to step 5:
The number 19 fits into 119 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 4756.0
Subtract 114 from 119 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 6:
When dividing 50 by 19, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 4756.2
Subtracting 38 from 50 leaves us 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.

Going ahead to step 7:
When dividing 120 by 19, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 4756.26
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.

Step 8:
When dividing 60 by 19, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 4756.263
Subtracting 57 from 60 leaves us 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.

Step 9:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 4756.2631
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
19 goes into 110 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4756.26315
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.

Step 11:
When dividing 150 by 19, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 4756.263157
Subtracting 133 from 150 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
170 divided by 19 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 4756.2631578
If we subtract 152 from 170, we 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.

On to step 13:
The number 19 fits into 180 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 4756.26315789
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 4756.26315789 with a remainder of 9e-09.
