We look at the division of 337374 by 19 
The aim is to understand the frequency of 19 in 337374.

Moving on to step 1:
3 divided by 19 is 0 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 (3) from the dividend after 3, then repeat: 33 / 19

Advancing to step 2:
33 divided by 19 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 19 from 33, we get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 19

On to step 3:
If we divide 147 by 19, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 133 from 147 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 19

Advancing to step 4:
143 divided by 19 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
If we subtract 133 from 143, we get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 19

On to step 5:
19 can be fit into 107 5 times, resulting in a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 1775.0
Subtracting 95 from 107 leaves us with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 19

Going ahead to step 6:
If we divide 124 by 19, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 17756.0
Deduct 114 from 124 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 19, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 17756.5
Subtracting 95 from 100 leaves us 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.

Let's proceed to step 8:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 17756.52
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.

Moving on to step 9:
19 goes into 120 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 17756.526
Subtracting 114 from 120 leaves us 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.

Step 10:
If we divide 60 by 19, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 17756.5263
Subtract 57 from 60 to 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.

Moving on to step 11:
19 goes into 30 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 17756.52631
Subtracting 19 from 30 leaves us 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.

Step 12:
19 goes into 110 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 17756.526315
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.

Step 13:
19 goes into 150 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17756.5263157
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.

Going ahead to step 14:
19 goes into 170 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 17756.52631578
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.

After the division, we end up with 17756.52631578 and a remainder of 1.8e-08.
