We're dividing 781596 by 72 
The aim is to understand the frequency of 72 in 781596.

Let's proceed to step 1:
72 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 72

Let's proceed to step 2:
72 goes into 78 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 72 from 78 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 72

Moving on to step 3:
The number 72 fits into 61 0 times, leaving a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 61 leaves us with 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 72

Advancing to step 4:
72 can be fit into 615 8 times, resulting in a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
The remainder is 39 after subtracting 576 from 615.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 72

Let's proceed to step 5:
72 goes into 399 5 times with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 1085.0
If we subtract 360 from 399, we get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 72

Advancing to step 6:
72 can be fit into 396 5 times, resulting in a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 10855.0
If we subtract 360 from 396, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
The number 72 fits into 360 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10855.5
The remainder is 0 after subtracting 360 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10855.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 72 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10855.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10855.5 with a remaining 0.0.
