299217 ÷ 19 
The aim is to understand the frequency of 19 in 299217.

Let's proceed to step 1:
When dividing 2 by 19, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 19

Step 2:
29 divided by 19 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 19 from 29, we get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 19

Let's proceed to step 3:
The number 19 fits into 109 5 times, leaving a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 95 from 109 and we're left with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 19

Moving on to step 4:
142 divided by 19 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we subtract 133 from 142, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 19

Going ahead to step 5:
91 divided by 19 is 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 1574.0
Deduct 76 from 91 and we're left with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 19

On to step 6:
19 can be fit into 157 8 times, resulting in a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 15748.0
Deduct 152 from 157 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.

Going ahead to step 7:
If we divide 50 by 19, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 15748.2
Deduct 38 from 50 and we're left 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.

Let's proceed to step 8:
If we divide 120 by 19, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 15748.26
Subtract 114 from 120 to 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 9:
If we divide 60 by 19, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 15748.263
If we subtract 57 from 60, we get 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 10:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 15748.2631
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.

Step 11:
If we divide 110 by 19, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15748.26315
Deduct 95 from 110 and we're left 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.

Let's proceed to step 12:
19 goes into 150 7 times with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 15748.263157
Subtract 133 from 150 to 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.

Moving on to step 13:
When dividing 170 by 19, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 15748.2631578
The remainder is 18 after subtracting 152 from 170.
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:
19 can be fit into 180 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 15748.26315789
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 15748.26315789 with a remainder of 9e-09.
