Let's divide 155224 by 72
The aim is to understand the frequency of 72 in 155224.

On to step 1:
1 divided by 72 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 72

On to step 2:
15 divided by 72 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 72

On to step 3:
155 divided by 72 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 144 from 155, we get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 72

Let's proceed to step 4:
When dividing 112 by 72, we get 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 72 from 112, we get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 72

Going ahead to step 5:
If we divide 402 by 72, we get 5 and a remainder of 42.
The next digit of our result is 5. 
Result so far: 215.0
If we subtract 360 from 402, we get 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 72

Let's proceed to step 6:
424 divided by 72 is 5 with a remainder of 64.
The next digit of our result is 5. 
Result so far: 2155.0
The remainder is 64 after subtracting 360 from 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
When dividing 640 by 72, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 2155.8
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.

Moving on to step 8:
72 can be fit into 640 8 times, resulting in a remainder of 64.
The next digit of our result is 8. 
Result so far: 2155.88
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.

Our division results in 2155.88 with a remaining 0.064.
