We look at the division of 859530 by 72 
The aim is to understand the frequency of 72 in 859530.

Advancing to step 1:
The number 72 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 72

Step 2:
When dividing 85 by 72, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 72 from 85 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 72

Moving on to step 3:
When dividing 139 by 72, we get 1 with a remainder of 67.
The next digit of our result is 1. 
Result so far: 11.0
If we take 72 away from 139, we end up with 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 72

Let's proceed to step 4:
675 divided by 72 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 119.0
The remainder is 27 after subtracting 648 from 675.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 72

Moving on to step 5:
The number 72 fits into 273 3 times, leaving a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 1193.0
Deduct 216 from 273 and we're left with 57.
Include the next digit (0) from the dividend after 57, then repeat: 570 / 72

Going ahead to step 6:
72 can be fit into 570 7 times, resulting in a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 11937.0
If we take 504 away from 570, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
The number 72 fits into 660 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 11937.9
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
120 divided by 72 is 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 11937.91
Deduct 72 from 120 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
72 goes into 480 6 times with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 11937.916
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 72, we get 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 11937.9166
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 11937.9166 with a balance of 0.00048.
