We divide 309230 by 19
The aim is to understand the frequency of 19 in 309230.

Advancing to step 1:
If we divide 3 by 19, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 19

Let's proceed to step 2:
The number 19 fits into 30 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 19 from 30, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 19

Step 3:
19 goes into 119 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 114 from 119, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 19

Step 4:
The number 19 fits into 52 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 162.0
The remainder is 14 after subtracting 38 from 52.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 19

Moving on to step 5:
143 divided by 19 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1627.0
If we take 133 away from 143, we end up with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 19

Advancing to step 6:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 16275.0
Deduct 95 from 100 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.

Moving on to step 7:
19 can be fit into 50 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 16275.2
The remainder is 12 after subtracting 38 from 50.
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 8:
120 divided by 19 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 16275.26
If we take 114 away from 120, we end up 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.

Let's proceed to step 9:
19 goes into 60 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 16275.263
Deduct 57 from 60 and we're left 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.

Advancing to step 10:
30 divided by 19 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 16275.2631
Deduct 19 from 30 and we're left 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 11:
19 can be fit into 110 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 16275.26315
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
The number 19 fits into 150 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 16275.263157
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.

Going ahead to step 13:
19 goes into 170 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 16275.2631578
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.

On to step 14:
180 divided by 19 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 16275.26315789
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.

After the division, we end up with 16275.26315789 and a remainder of 9e-09.
