884306 ÷ 45 
The aim is to understand the frequency of 45 in 884306.

Step 1:
45 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 45

Moving on to step 2:
If we divide 88 by 45, we get 1 and a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 45 away from 88, we end up with 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 45

Moving on to step 3:
45 can be fit into 434 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 405 from 434 to get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 45

Advancing to step 4:
The number 45 fits into 293 6 times, leaving a remainder of 23.
The next digit of our result is 6. 
Result so far: 196.0
If we take 270 away from 293, we end up with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 45

Advancing to step 5:
When dividing 230 by 45, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1965.0
The remainder is 5 after subtracting 225 from 230.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 45

Let's proceed to step 6:
The number 45 fits into 56 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 19651.0
If we subtract 45 from 56, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
The number 45 fits into 110 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 19651.2
The remainder is 20 after subtracting 90 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 45 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 19651.24
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 19651.244
If we subtract 180 from 200, we 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 outcome is 19651.244, with a leftover of 0.002.
