We divide 72140 by 8
The aim is to understand the frequency of 8 in 72140.

Let's proceed to step 1:
8 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 8

On to step 2:
72 divided by 8 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 72 from 72 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 8

Step 3:
When dividing 1 by 8, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 90.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 8

On to step 4:
8 goes into 14 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 901.0
Deduct 8 from 14 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 8

On to step 5:
The number 8 fits into 60 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 9017.0
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 6:
8 can be fit into 40 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9017.5
If we subtract 40 from 40, 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.

Let's proceed to step 7:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9017.5
Subtract 0 from 0 to 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.

Let's proceed to step 8:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9017.5
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 9017.5 with a remaining 0.0.
