We look at the division of 60549509 by 216 
The aim is to understand the frequency of 216 in 60549509.

Moving on to step 1:
The number 216 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 216

On to step 2:
The number 216 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 216

Step 3:
If we divide 605 by 216, we get 2 and a remainder of 173.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 432 from 605, we get 173.
Bring next digit (4) of the dividend behind the 173 and repeat the process: 1734 / 216

Going ahead to step 4:
1734 divided by 216 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 1728 away from 1734, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 216

On to step 5:
216 can be fit into 69 0 times, resulting in a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 280.0
Subtracting 0 from 69 leaves us with 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 216

Moving on to step 6:
If we divide 695 by 216, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 2803.0
Subtracting 648 from 695 leaves us with 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 216

Let's proceed to step 7:
470 divided by 216 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 28032.0
The remainder is 38 after subtracting 432 from 470.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 216

Step 8:
When dividing 389 by 216, we get 1 with a remainder of 173.
The next digit of our result is 1. 
Result so far: 280321.0
Subtracting 216 from 389 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 9:
If we divide 1730 by 216, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 280321.8
Subtract 1728 from 1730 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 216, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 280321.8
If we subtract 0 from 20, we 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.

Moving on to step 11:
The number 216 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 280321.8
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 280321.8 with a remainder of 0.02.
