We look at the division of 863053 by 72 
The aim is to understand the frequency of 72 in 863053.

Moving on to step 1:
When dividing 8 by 72, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 72

Let's proceed to step 2:
The number 72 fits into 86 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 14 after subtracting 72 from 86.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 72

Advancing to step 3:
72 goes into 143 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 72 from 143 to get 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 72

Advancing to step 4:
710 divided by 72 is 9 with a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Subtracting 648 from 710 leaves us with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 72

Moving on to step 5:
If we divide 625 by 72, we get 8 and a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 1198.0
If we subtract 576 from 625, we get 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 72

Moving on to step 6:
If we divide 493 by 72, we get 6 and a remainder of 61.
Record the quotient 6 as the next digit in the result. 
Result so far: 11986.0
Subtracting 432 from 493 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
When dividing 610 by 72, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 11986.8
Deduct 576 from 610 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
The number 72 fits into 340 4 times, leaving a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 11986.84
The remainder is 52 after subtracting 288 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
72 can be fit into 520 7 times, resulting in a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 11986.847
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.

Moving on to step 10:
The number 72 fits into 160 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 11986.8472
If we subtract 144 from 160, we 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.

On to step 11:
160 divided by 72 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 11986.84722
If we subtract 144 from 160, we 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.

In conclusion, the division gives 11986.84722 with a balance of 1.6e-05.
