We're dividing 832225 by 72 
The aim is to understand the frequency of 72 in 832225.

Advancing to step 1:
8 divided by 72 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 72

Going ahead to step 2:
The number 72 fits into 83 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 72 from 83, we get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 72

On to step 3:
72 goes into 112 1 times with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 72 from 112 leaves us with 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 72

On to step 4:
402 divided by 72 is 5 with a remainder of 42.
Write down 5 as next digit of the result. 
Result so far: 115.0
The remainder is 42 after subtracting 360 from 402.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 72

Moving on to step 5:
72 goes into 422 5 times with a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 1155.0
The remainder is 62 after subtracting 360 from 422.
Take the next digit (5) from the dividend and append it to 62, then repeat: 625 / 72

Step 6:
When dividing 625 by 72, we get 8 with a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 11558.0
Deduct 576 from 625 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
72 can be fit into 490 6 times, resulting in a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 11558.6
Deduct 432 from 490 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
When dividing 580 by 72, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 11558.68
The remainder is 4 after subtracting 576 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
72 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 11558.68
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 72, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 11558.6805
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
If we divide 400 by 72, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 11558.68055
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 11558.68055 with a remaining 4e-05.
