We're dividing 53218 by 72 
The aim is to understand the frequency of 72 in 53218.

Moving on to step 1:
The number 72 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 72

Advancing to step 2:
72 can be fit into 53 0 times, resulting in a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 72

On to step 3:
When dividing 532 by 72, we get 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 504 from 532 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 72

Moving on to step 4:
If we divide 281 by 72, we get 3 and a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we take 216 away from 281, we end up with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 72

Going ahead to step 5:
If we divide 658 by 72, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 739.0
Subtracting 648 from 658 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 6:
100 divided by 72 is 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 739.1
If we subtract 72 from 100, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
72 can be fit into 280 3 times, resulting in a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 739.13
Subtracting 216 from 280 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 739.138
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
640 divided by 72 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 739.1388
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 739.1388 with a balance of 0.00064.
