413378 divided by 19 
The aim is to understand the frequency of 19 in 413378.

On to step 1:
When dividing 4 by 19, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 19

Advancing to step 2:
19 goes into 41 2 times with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 38 from 41, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 19

On to step 3:
When dividing 33 by 19, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 19 from 33, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 19

Going ahead to step 4:
The number 19 fits into 143 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Subtract 133 from 143 to get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 19

Going ahead to step 5:
If we divide 107 by 19, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 2175.0
The remainder is 12 after subtracting 95 from 107.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 19

On to step 6:
19 can be fit into 128 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 21756.0
If we take 114 away from 128, we end up 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.

Step 7:
19 can be fit into 140 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 21756.7
Subtract 133 from 140 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
When dividing 70 by 19, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 21756.73
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 9:
When dividing 130 by 19, we get 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 21756.736
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 19, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 21756.7368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 21756.73684
If we take 76 away from 80, we end up with 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 12:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 21756.736842
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
19 goes into 20 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 21756.7368421
Subtracting 19 from 20 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
If we divide 10 by 19, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21756.7368421
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 21756.7368421 with a remainder of 1e-08.
