We're dividing 820182 by 72 
The aim is to understand the frequency of 72 in 820182.

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
Subtracting 0 from 8 leaves us with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 72

Advancing to step 2:
The number 72 fits into 82 1 times, leaving a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 10 after subtracting 72 from 82.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 72

Let's proceed to step 3:
When dividing 100 by 72, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 11.0
If we take 72 away from 100, we end up with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 72

Moving on to step 4:
If we divide 281 by 72, we get 3 and a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we take 216 away from 281, we end up with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 72

Let's proceed to step 5:
72 can be fit into 658 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 1139.0
Subtracting 648 from 658 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 72

Let's proceed to step 6:
If we divide 102 by 72, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 11391.0
Subtract 72 from 102 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
The number 72 fits into 300 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 11391.4
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
If we divide 120 by 72, we get 1 and a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 11391.41
The remainder is 48 after subtracting 72 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
The number 72 fits into 480 6 times, leaving a remainder of 48.
The next digit of our result is 6. 
Result so far: 11391.416
If we subtract 432 from 480, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 11391.4166
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 11391.4166 and a remainder of 0.00048.
