We're dividing 98787665 by 45 
The aim is to understand the frequency of 45 in 98787665.

Let's proceed to step 1:
9 divided by 45 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 45

Moving on to step 2:
45 can be fit into 98 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 90 from 98 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 45

Step 3:
If we divide 87 by 45, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 42 after subtracting 45 from 87.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 45

On to step 4:
The number 45 fits into 428 9 times, leaving a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
If we take 405 away from 428, we end up with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 45

Let's proceed to step 5:
45 goes into 237 5 times with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 2195.0
Deduct 225 from 237 and we're left with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 45

Let's proceed to step 6:
If we divide 126 by 45, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 21952.0
Subtracting 90 from 126 leaves us with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 45

Let's proceed to step 7:
366 divided by 45 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 219528.0
Subtract 360 from 366 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 45

Moving on to step 8:
When dividing 65 by 45, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 2195281.0
The remainder is 20 after subtracting 45 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
45 goes into 200 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 2195281.4
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.

Let's proceed to step 10:
If we divide 200 by 45, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 2195281.44
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.

The final result is 2195281.44 with a remainder of 0.02.
