Let's divide 256435 by 19
The aim is to understand the frequency of 19 in 256435.

Moving on to step 1:
19 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 19

Let's proceed to step 2:
19 can be fit into 25 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 19 away from 25, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 19

Step 3:
19 goes into 66 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 57 away from 66, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 19

Let's proceed to step 4:
94 divided by 19 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 134.0
The remainder is 18 after subtracting 76 from 94.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 19

On to step 5:
19 goes into 183 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 1349.0
If we take 171 away from 183, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 19

Going ahead to step 6:
The number 19 fits into 125 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 13496.0
Subtract 114 from 125 to 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.

Let's proceed to step 7:
When dividing 110 by 19, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 13496.5
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.

Step 8:
The number 19 fits into 150 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 13496.57
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.

Advancing to step 9:
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: 13496.578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
19 goes into 180 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 13496.5789
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 13496.57894
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.

Let's proceed to step 12:
When dividing 140 by 19, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 13496.578947
Subtracting 133 from 140 leaves us with 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 13:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 13496.5789473
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
If we divide 130 by 19, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 13496.57894736
Subtracting 114 from 130 leaves us 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.

Our division results in 13496.57894736 with a remaining 1.6e-08.
