239353 ÷ 19 
The aim is to understand the frequency of 19 in 239353.

On to step 1:
19 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 19

Moving on to step 2:
23 divided by 19 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 19 from 23 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 19

On to step 3:
The number 19 fits into 49 2 times, leaving a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 38 from 49, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 19

Let's proceed to step 4:
113 divided by 19 is 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 125.0
If we subtract 95 from 113, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 19

On to step 5:
The number 19 fits into 185 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 1259.0
If we take 171 away from 185, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 19

Let's proceed to step 6:
The number 19 fits into 143 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 12597.0
The remainder is 10 after subtracting 133 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 19, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12597.5
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.

Going ahead to step 8:
If we divide 50 by 19, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12597.52
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.

On to step 9:
120 divided by 19 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 12597.526
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.

Step 10:
19 goes into 60 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 12597.5263
Subtracting 57 from 60 leaves us with 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:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 12597.52631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
110 divided by 19 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12597.526315
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
19 goes into 150 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 12597.5263157
If we take 133 away from 150, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
If we divide 170 by 19, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 12597.52631578
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 12597.52631578 with a balance of 1.8e-08.
