302348 ÷ 45 
The aim is to understand the frequency of 45 in 302348.

Advancing to step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 45

Advancing to step 2:
45 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 45

On to step 3:
If we divide 302 by 45, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 270 from 302 and we're left with 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 45

On to step 4:
323 divided by 45 is 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 67.0
If we take 315 away from 323, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 45

Let's proceed to step 5:
84 divided by 45 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 671.0
If we subtract 45 from 84, we get 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 45

Going ahead to step 6:
398 divided by 45 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 6718.0
If we take 360 away from 398, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
When dividing 380 by 45, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 6718.8
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 6718.84
Subtract 180 from 200 to 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.

Let's proceed to step 9:
45 goes into 200 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 6718.844
Subtract 180 from 200 to 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.

The final result is 6718.844 with a remainder of 0.002.
