613366 divided by 72 
The aim is to understand the frequency of 72 in 613366.

Going ahead to step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 72

On to step 2:
61 divided by 72 is 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Grab the next digit (3) from the dividend, add it to 61, then carry on: 613 / 72

On to step 3:
The number 72 fits into 613 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 37 after subtracting 576 from 613.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 72

On to step 4:
If we divide 373 by 72, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we take 360 away from 373, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 72

Moving on to step 5:
If we divide 136 by 72, we get 1 and a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 851.0
If we take 72 away from 136, we end up with 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 72

Going ahead to step 6:
When dividing 646 by 72, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 8518.0
If we take 576 away from 646, 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.

Let's proceed to step 7:
The number 72 fits into 700 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 8518.9
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.

Moving on to step 8:
The number 72 fits into 520 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 8518.97
Deduct 504 from 520 and we're left 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.

Advancing to step 9:
160 divided by 72 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 8518.972
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.

Going ahead to step 10:
If we divide 160 by 72, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 8518.9722
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.

The final outcome is 8518.9722, with a leftover of 0.00016.
