We look at the division of 720050 by 19 
The aim is to understand the frequency of 19 in 720050.

Going ahead to step 1:
The number 19 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 19

Going ahead to step 2:
The number 19 fits into 72 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
If we take 57 away from 72, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 19

Step 3:
When dividing 150 by 19, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 37.0
If we take 133 away from 150, we end up with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 19

Let's proceed to step 4:
If we divide 170 by 19, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 378.0
The remainder is 18 after subtracting 152 from 170.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 19

On to step 5:
When dividing 185 by 19, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 3789.0
Subtracting 171 from 185 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 19

On to step 6:
If we divide 140 by 19, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 37897.0
If we take 133 away from 140, we end up 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 7:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 37897.3
Deduct 57 from 70 and we're left 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.

Going ahead to step 8:
The number 19 fits into 130 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 37897.36
Subtract 114 from 130 to get 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 9:
When dividing 160 by 19, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 37897.368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 19 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 37897.3684
Subtract 76 from 80 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
40 divided by 19 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 37897.36842
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
20 divided by 19 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 37897.368421
Subtracting 19 from 20 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
10 divided by 19 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 37897.368421
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.

Advancing to step 14:
100 divided by 19 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 37897.36842105
If we take 95 away from 100, we end up 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.

The final outcome is 37897.36842105, with a leftover of 5e-09.
