We're dividing 171082 by 72 
The aim is to understand the frequency of 72 in 171082.

Moving on to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 72

Going ahead to step 2:
72 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 72

Let's proceed to step 3:
If we divide 171 by 72, we get 2 and a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 144 from 171, we get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 72

On to step 4:
270 divided by 72 is 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 54 after subtracting 216 from 270.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 72

Advancing to step 5:
72 can be fit into 548 7 times, resulting in a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 237.0
If we take 504 away from 548, we end up with 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 72

Going ahead to step 6:
442 divided by 72 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 2376.0
Deduct 432 from 442 and we're left 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 7:
72 goes into 100 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 2376.1
If we take 72 away from 100, we end up with 28.
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 8:
The number 72 fits into 280 3 times, leaving a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 2376.13
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.

Advancing to step 9:
640 divided by 72 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 2376.138
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
If we divide 640 by 72, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 2376.1388
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 2376.1388 with a remaining 0.00064.
