We look at the division of 803065 by 72 
The aim is to understand the frequency of 72 in 803065.

On to step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 72

Moving on to step 2:
The number 72 fits into 80 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 72 from 80, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 72

Step 3:
When dividing 83 by 72, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 72 from 83 to get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 72

Moving on to step 4:
72 goes into 110 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 111.0
If we take 72 away from 110, we end up with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 72

Let's proceed to step 5:
386 divided by 72 is 5 with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 1115.0
Subtracting 360 from 386 leaves us with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 72

Step 6:
72 can be fit into 265 3 times, resulting in a remainder of 49.
The next digit of our result is 3. 
Result so far: 11153.0
Deduct 216 from 265 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:
If we divide 490 by 72, we get 6 and a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 11153.6
If we take 432 away from 490, we end up 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.

Going ahead 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: 11153.68
If we take 576 away from 580, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 72, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11153.68
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.
Record the quotient 5 as the next digit in the result. 
Result so far: 11153.6805
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.
The next digit of our result is 5. 
Result so far: 11153.68055
If we take 360 away from 400, we end up 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 11153.68055 with a remaining 4e-05.
