350217 divided by 19 
The aim is to understand the frequency of 19 in 350217.

Moving on to step 1:
19 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 19

Moving on to step 2:
35 divided by 19 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 19 from 35 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 19

Going ahead to step 3:
If we divide 160 by 19, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 152 from 160 leaves us with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 19

Step 4:
82 divided by 19 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
Subtracting 76 from 82 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 19

On to step 5:
When dividing 61 by 19, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 1843.0
Subtract 57 from 61 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 19

Going ahead to step 6:
47 divided by 19 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 18432.0
Deduct 38 from 47 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.

Moving on to step 7:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 18432.4
Deduct 76 from 90 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 18432.47
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 18432.473
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 18432.4736
If we take 114 away from 130, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 19 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 18432.47368
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
19 goes into 80 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 18432.473684
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
19 goes into 40 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 18432.4736842
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
The number 19 fits into 20 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 18432.47368421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 18432.47368421 with a remaining 1e-09.
