66352928 divided by 218 
The aim is to understand the frequency of 218 in 66352928.

On to step 1:
218 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 218

Advancing to step 2:
The number 218 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 218

Going ahead to step 3:
If we divide 663 by 218, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 654 from 663 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 218

On to step 4:
218 goes into 95 0 times with a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 95, we end up with 95.
Bring next digit (2) of the dividend behind the 95 and repeat the process: 952 / 218

Advancing to step 5:
218 can be fit into 952 4 times, resulting in a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
If we take 872 away from 952, we end up with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 218

Let's proceed to step 6:
218 can be fit into 809 3 times, resulting in a remainder of 155.
Record the quotient 3 as the next digit in the result. 
Result so far: 3043.0
Subtracting 654 from 809 leaves us with 155.
Bring next digit (2) of the dividend behind the 155 and repeat the process: 1552 / 218

Going ahead to step 7:
218 goes into 1552 7 times with a remainder of 26.
The next digit of our result is 7. 
Result so far: 30437.0
If we take 1526 away from 1552, we end up with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 218

On to step 8:
218 goes into 268 1 times with a remainder of 50.
The next digit of our result is 1. 
Result so far: 304371.0
If we take 218 away from 268, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
When dividing 500 by 218, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 304371.2
If we subtract 436 from 500, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
640 divided by 218 is 2 with a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 304371.22
Subtract 436 from 640 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final result is 304371.22 with a remainder of 0.204.
