239758 divided by 19 
The aim is to understand the frequency of 19 in 239758.

Let's proceed to step 1:
2 divided by 19 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 19

Moving on to step 2:
19 can be fit into 23 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 19 from 23, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 19

Going ahead to step 3:
The number 19 fits into 49 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 38 from 49 leaves us with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 19

On to step 4:
If we divide 117 by 19, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 126.0
The remainder is 3 after subtracting 114 from 117.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 19

Let's proceed to step 5:
When dividing 35 by 19, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1261.0
If we take 19 away from 35, we end up with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 19

Advancing to step 6:
When dividing 168 by 19, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 12618.0
Deduct 152 from 168 and we're left 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.

Going ahead to step 7:
160 divided by 19 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 12618.8
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:
80 divided by 19 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 12618.84
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
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: 12618.842
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
19 goes into 20 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 12618.8421
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12618.8421
Subtract 0 from 10 to 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.

Moving on to step 12:
If we divide 100 by 19, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12618.842105
If we subtract 95 from 100, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
When dividing 50 by 19, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12618.8421052
Subtracting 38 from 50 leaves us 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 14:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 12618.84210526
Deduct 114 from 120 and we're left 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.

Our division results in 12618.84210526 with a remaining 6e-09.
