Let's divide 18649148 by 45
The aim is to understand the frequency of 45 in 18649148.

Advancing to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 45

Let's proceed to step 2:
45 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 45

Advancing to step 3:
45 goes into 186 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 180 from 186, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 45

On to step 4:
When dividing 64 by 45, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 45 from 64 leaves us with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 45

Going ahead to step 5:
If we divide 199 by 45, we get 4 and a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 414.0
The remainder is 19 after subtracting 180 from 199.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 45

On to step 6:
45 goes into 191 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4144.0
If we take 180 away from 191, we end up with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 45

Step 7:
45 can be fit into 114 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 41442.0
The remainder is 24 after subtracting 90 from 114.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 45

Step 8:
248 divided by 45 is 5 with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 414425.0
Subtracting 225 from 248 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
45 goes into 230 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 414425.5
Deduct 225 from 230 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
When dividing 50 by 45, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 414425.51
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
When dividing 50 by 45, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 414425.511
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 414425.511 with a balance of 0.0005.
