We divide 72330525 by 218
The aim is to understand the frequency of 218 in 72330525.

Moving on to step 1:
218 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 218

Going ahead to step 2:
218 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 218

Let's proceed to step 3:
When dividing 723 by 218, we get 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 69 after subtracting 654 from 723.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 218

Let's proceed to step 4:
If we divide 693 by 218, we get 3 and a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Subtracting 654 from 693 leaves us with 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 218

Moving on to step 5:
390 divided by 218 is 1 with a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 331.0
Deduct 218 from 390 and we're left with 172.
Take the next digit (5) from the dividend and append it to 172, then repeat: 1725 / 218

Going ahead to step 6:
218 can be fit into 1725 7 times, resulting in a remainder of 199.
Put 7 as the next digit of the answer. 
Result so far: 3317.0
Deduct 1526 from 1725 and we're left with 199.
Append the next digit (2) from the dividend to 199 and continue with: 1992 / 218

Advancing to step 7:
When dividing 1992 by 218, we get 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 33179.0
The remainder is 30 after subtracting 1962 from 1992.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 218

Let's proceed to step 8:
218 can be fit into 305 1 times, resulting in a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 331791.0
Subtract 218 from 305 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
218 can be fit into 870 3 times, resulting in a remainder of 216.
The number 3 becomes the next digit in our result. 
Result so far: 331791.3
Subtracting 654 from 870 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 10:
When dividing 2160 by 218, we get 9 with a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 331791.39
Subtract 1962 from 2160 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 11:
218 can be fit into 1980 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 331791.399
If we take 1962 away from 1980, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 331791.399, with a leftover of 0.0018.
