889580 ÷ 72 
The aim is to understand the frequency of 72 in 889580.

On to step 1:
8 divided by 72 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 72

Going ahead to step 2:
72 can be fit into 88 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 72 away from 88, we end up with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 72

Let's proceed to step 3:
169 divided by 72 is 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 144 away from 169, we end up with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 72

On to step 4:
When dividing 255 by 72, we get 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtract 216 from 255 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 72

On to step 5:
72 can be fit into 398 5 times, resulting in a remainder of 38.
The next digit of our result is 5. 
Result so far: 1235.0
If we take 360 away from 398, we end up with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 72

Going ahead to step 6:
When dividing 380 by 72, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 12355.0
Subtract 360 from 380 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
72 goes into 200 2 times with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 12355.2
If we subtract 144 from 200, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
72 can be fit into 560 7 times, resulting in a remainder of 56.
The next digit of our result is 7. 
Result so far: 12355.27
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
When dividing 560 by 72, we get 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 12355.277
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 12355.277 with a remainder of 0.0056.
