767248 ÷ 72 
The aim is to understand the frequency of 72 in 767248.

On to step 1:
7 divided by 72 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 72

On to step 2:
The number 72 fits into 76 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 72 from 76 to get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 72

Advancing to step 3:
72 goes into 47 0 times with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 47 to get 47.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 72

Going ahead to step 4:
472 divided by 72 is 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtracting 432 from 472 leaves us with 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 72

Advancing to step 5:
404 divided by 72 is 5 with a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 1065.0
The remainder is 44 after subtracting 360 from 404.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 72

Step 6:
If we divide 448 by 72, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10656.0
If we take 432 away from 448, we end up 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.

Going ahead to step 7:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 10656.2
Subtract 144 from 160 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.

Step 8:
If we divide 160 by 72, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 10656.22
Deduct 144 from 160 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.

Our division results in 10656.22 with a remaining 0.016.
