727996 ÷ 19 
The aim is to understand the frequency of 19 in 727996.

Advancing to step 1:
The number 19 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 19

Advancing to step 2:
When dividing 72 by 19, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 57 from 72, we get 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 19

Going ahead to step 3:
19 can be fit into 157 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 38.0
If we take 152 away from 157, we end up with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 19

Moving on to step 4:
When dividing 59 by 19, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 383.0
Subtracting 57 from 59 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 19

Advancing to step 5:
When dividing 29 by 19, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 3831.0
Deduct 19 from 29 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 19

On to step 6:
The number 19 fits into 106 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 38315.0
If we take 95 away from 106, we end up with 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:
110 divided by 19 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 38315.5
Subtract 95 from 110 to get 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 8:
If we divide 150 by 19, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 38315.57
Subtracting 133 from 150 leaves us 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.

Step 9:
The number 19 fits into 170 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 38315.578
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 10:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 38315.5789
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.

On to step 11:
19 goes into 90 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 38315.57894
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
19 goes into 140 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 38315.578947
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.

Going ahead to step 13:
When dividing 70 by 19, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 38315.5789473
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
If we divide 130 by 19, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 38315.57894736
Deduct 114 from 130 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.

Our division results in 38315.57894736 with a remaining 1.6e-08.
