431265 ÷ 19 
The aim is to understand the frequency of 19 in 431265.

Step 1:
If we divide 4 by 19, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 19

Let's proceed to step 2:
43 divided by 19 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 5 after subtracting 38 from 43.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 19

Going ahead to step 3:
19 can be fit into 51 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 38 away from 51, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 19

Advancing to step 4:
132 divided by 19 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 226.0
Subtract 114 from 132 to get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 19

Going ahead to step 5:
When dividing 186 by 19, we get 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 2269.0
Deduct 171 from 186 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 19

Let's proceed to step 6:
19 can be fit into 155 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 22698.0
Subtracting 152 from 155 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.

On to step 7:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 22698.1
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22698.15
Deduct 95 from 110 and we're left 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 9:
The number 19 fits into 150 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 22698.157
If we subtract 133 from 150, we 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.

Moving on to step 10:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 22698.1578
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.

Going ahead to step 11:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 22698.15789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
90 divided by 19 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 22698.157894
If we take 76 away from 90, 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 13:
140 divided by 19 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 22698.1578947
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.

Advancing to step 14:
19 goes into 70 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 22698.15789473
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.

The final result is 22698.15789473 with a remainder of 1.3e-08.
