820519 divided by 72 
The aim is to understand the frequency of 72 in 820519.

Let's proceed to step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 72

Going ahead to step 2:
When dividing 82 by 72, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 72 from 82, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 72

Let's proceed to step 3:
The number 72 fits into 100 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 72 from 100, we get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 72

Step 4:
285 divided by 72 is 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 113.0
Subtract 216 from 285 to get 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 72

On to step 5:
691 divided by 72 is 9 with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 1139.0
If we subtract 648 from 691, we get 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 72

Advancing to step 6:
72 can be fit into 439 6 times, resulting in a remainder of 7.
The next digit of our result is 6. 
Result so far: 11396.0
Subtracting 432 from 439 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.

Let's proceed to step 7:
When dividing 70 by 72, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 11396.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
72 goes into 700 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 11396.09
Subtracting 648 from 700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
72 can be fit into 520 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 11396.097
Subtract 504 from 520 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.

Let's proceed to step 10:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 11396.0972
Subtracting 144 from 160 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.

Let's proceed to step 11:
72 goes into 160 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 11396.09722
Subtract 144 from 160 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.

The final outcome is 11396.09722, with a leftover of 1.6e-05.
