We're dividing 65900336 by 218 
The aim is to understand the frequency of 218 in 65900336.

Step 1:
When dividing 6 by 218, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 218

Going ahead to step 2:
If we divide 65 by 218, we get 0 and a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 218

Going ahead to step 3:
218 can be fit into 659 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 654 away from 659, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 218

Step 4:
218 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 50, we end up with 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 218

Moving on to step 5:
218 can be fit into 500 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 302.0
Subtract 436 from 500 to get 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 218

Moving on to step 6:
The number 218 fits into 643 2 times, leaving a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 3022.0
If we subtract 436 from 643, we get 207.
Bring next digit (3) of the dividend behind the 207 and repeat the process: 2073 / 218

Moving on to step 7:
218 can be fit into 2073 9 times, resulting in a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 30229.0
Subtract 1962 from 2073 to get 111.
Take the next digit (6) from the dividend and append it to 111, then repeat: 1116 / 218

Let's proceed to step 8:
1116 divided by 218 is 5 with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 302295.0
The remainder is 26 after subtracting 1090 from 1116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
If we divide 260 by 218, we get 1 and a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 302295.1
If we subtract 218 from 260, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
The number 218 fits into 420 1 times, leaving a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 302295.11
Deduct 218 from 420 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final result is 302295.11 with a remainder of 0.202.
