725033 divided by 19 
The aim is to understand the frequency of 19 in 725033.

Moving on to step 1:
If we divide 7 by 19, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 19

Moving on to step 2:
The number 19 fits into 72 3 times, leaving a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 57 from 72 leaves us with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 19

Advancing to step 3:
The number 19 fits into 155 8 times, leaving a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 152 from 155 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 19

Step 4:
If we divide 30 by 19, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 381.0
If we subtract 19 from 30, we get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 19

Let's proceed to step 5:
19 can be fit into 113 5 times, resulting in a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 3815.0
If we take 95 away from 113, we end up with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 19

Let's proceed to step 6:
183 divided by 19 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 38159.0
If we take 171 away from 183, we end up 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.

Going ahead to step 7:
120 divided by 19 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 38159.6
Subtracting 114 from 120 leaves us 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.

On to step 8:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 38159.63
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
If we divide 30 by 19, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 38159.631
Deduct 19 from 30 and we're left 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.

Going ahead to step 10:
The number 19 fits into 110 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 38159.6315
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 11:
19 goes into 150 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 38159.63157
Subtract 133 from 150 to 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.

On to step 12:
19 goes into 170 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 38159.631578
Subtract 152 from 170 to get 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 13:
19 goes into 180 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 38159.6315789
If we take 171 away from 180, we end up 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 14:
If we divide 90 by 19, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 38159.63157894
Subtracting 76 from 90 leaves us 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.

The final result is 38159.63157894 with a remainder of 1.4e-08.
