We're dividing 570997 by 72 
The aim is to understand the frequency of 72 in 570997.

On to step 1:
5 divided by 72 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 72

Let's proceed to step 2:
When dividing 57 by 72, we get 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 72

Step 3:
72 can be fit into 570 7 times, resulting in a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 504 from 570 and we're left with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 72

Going ahead to step 4:
669 divided by 72 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 648 from 669 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 72

Let's proceed to step 5:
When dividing 219 by 72, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 793.0
Subtract 216 from 219 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 72

Let's proceed to step 6:
72 goes into 37 0 times with a remainder of 37.
The next digit of our result is 0. 
Result so far: 7930.0
If we subtract 0 from 37, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
370 divided by 72 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7930.5
If we take 360 away from 370, we end up 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 8:
100 divided by 72 is 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 7930.51
The remainder is 28 after subtracting 72 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 72, we get 3 with a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 7930.513
The remainder is 64 after subtracting 216 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
640 divided by 72 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 7930.5138
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 7930.51388
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 7930.51388 and a remainder of 6.4e-05.
