We divide 177580 by 72
The aim is to understand the frequency of 72 in 177580.

Going ahead to step 1:
72 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 72

Let's proceed to step 2:
72 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 72

Step 3:
When dividing 177 by 72, we get 2 with a remainder of 33.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 144 from 177 leaves us with 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 72

Moving on to step 4:
72 goes into 335 4 times with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 288 from 335 and we're left with 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 72

On to step 5:
When dividing 478 by 72, we get 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 246.0
If we take 432 away from 478, we end up with 46.
Take the next digit (0) from the dividend and append it to 46, then repeat: 460 / 72

On to step 6:
The number 72 fits into 460 6 times, leaving a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 2466.0
The remainder is 28 after subtracting 432 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
When dividing 280 by 72, we get 3 with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 2466.3
If we take 216 away from 280, we end up 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.

Advancing to step 8:
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: 2466.38
Subtracting 576 from 640 leaves us 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.

On to step 9:
If we divide 640 by 72, we get 8 and a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 2466.388
Subtracting 576 from 640 leaves us 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.

The final result is 2466.388 with a remainder of 0.0064.
