We look at the division of 438954 by 19 
The aim is to understand the frequency of 19 in 438954.

Let's proceed to step 1:
The number 19 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 19

Moving on to step 2:
The number 19 fits into 43 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 38 from 43 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 19

Advancing to step 3:
19 can be fit into 58 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 57 from 58 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 19

Moving on to step 4:
The number 19 fits into 19 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
Subtracting 19 from 19 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 19

Step 5:
5 divided by 19 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 2310.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 19

On to step 6:
19 goes into 54 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 23102.0
Subtract 38 from 54 to 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.

Advancing to step 7:
The number 19 fits into 160 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 23102.8
Subtracting 152 from 160 leaves us 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.

Advancing to step 8:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 23102.84
Deduct 76 from 80 and we're left 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 9:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 23102.842
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.

Advancing to step 10:
When dividing 20 by 19, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 23102.8421
Deduct 19 from 20 and we're left 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.

Let's proceed to step 11:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 23102.8421
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 12:
When dividing 100 by 19, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 23102.842105
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.

Let's proceed to step 13:
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: 23102.8421052
If we take 38 away from 50, we end up 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.

On to step 14:
120 divided by 19 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 23102.84210526
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.

The quotient of the division is 23102.84210526, and the remainder is 6e-09.
