We look at the division of 32646115 by 305 
The aim is to understand the frequency of 305 in 32646115.

On to step 1:
305 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 305

On to step 2:
If we divide 32 by 305, we get 0 and a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 305

On to step 3:
When dividing 326 by 305, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 21 after subtracting 305 from 326.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 305

Going ahead to step 4:
305 can be fit into 214 0 times, resulting in a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 214 leaves us with 214.
Grab the next digit (6) from the dividend, add it to 214, then carry on: 2146 / 305

Advancing to step 5:
If we divide 2146 by 305, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we take 2135 away from 2146, we end up with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 305

Moving on to step 6:
305 can be fit into 111 0 times, resulting in a remainder of 111.
The number 0 becomes the next digit in our result. 
Result so far: 1070.0
The remainder is 111 after subtracting 0 from 111.
Include the next digit (1) from the dividend after 111, then repeat: 1111 / 305

Advancing to step 7:
When dividing 1111 by 305, we get 3 with a remainder of 196.
Put 3 as the next digit of the answer. 
Result so far: 10703.0
Subtract 915 from 1111 to get 196.
Append the next digit (5) from the dividend to 196 and continue with: 1965 / 305

On to step 8:
When dividing 1965 by 305, we get 6 with a remainder of 135.
The number 6 becomes the next digit in our result. 
Result so far: 107036.0
Deduct 1830 from 1965 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
If we divide 1350 by 305, we get 4 and a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 107036.4
Subtract 1220 from 1350 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
If we divide 1300 by 305, we get 4 and a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 107036.44
If we subtract 1220 from 1300, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 107036.44 with a remainder of 0.08.
