Let's divide 48258866 by 45
The aim is to understand the frequency of 45 in 48258866.

Advancing to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 45

Moving on to step 2:
45 can be fit into 48 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 45 away from 48, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 45

Going ahead to step 3:
45 can be fit into 32 0 times, resulting in a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 32 and we're left with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 45

Moving on to step 4:
The number 45 fits into 325 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 107.0
If we subtract 315 from 325, we get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 45

On to step 5:
45 goes into 108 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1072.0
If we take 90 away from 108, we end up with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 45

Step 6:
If we divide 188 by 45, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 10724.0
The remainder is 8 after subtracting 180 from 188.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 45

Going ahead to step 7:
86 divided by 45 is 1 with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 107241.0
Subtracting 45 from 86 leaves us with 41.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 45

Advancing to step 8:
If we divide 416 by 45, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 1072419.0
If we subtract 405 from 416, 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.

Step 9:
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: 1072419.2
Deduct 90 from 110 and we're left 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.

On to step 10:
If we divide 200 by 45, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 1072419.24
Subtracting 180 from 200 leaves us 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 11:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 1072419.244
Deduct 180 from 200 and we're left 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.

After the division, we end up with 1072419.244 and a remainder of 0.002.
