We're dividing 43068417 by 45 
The aim is to understand the frequency of 45 in 43068417.

Advancing to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 45

Advancing to step 2:
45 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 45

Step 3:
The number 45 fits into 430 9 times, leaving a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 405 from 430 to get 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 45

On to step 4:
45 can be fit into 256 5 times, resulting in a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtract 225 from 256 to get 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 45

Moving on to step 5:
45 goes into 318 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 957.0
If we subtract 315 from 318, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 45

Moving on to step 6:
If we divide 34 by 45, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 9570.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 45

Advancing to step 7:
The number 45 fits into 341 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 95707.0
If we take 315 away from 341, we end up with 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 45

Step 8:
267 divided by 45 is 5 with a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 957075.0
Subtracting 225 from 267 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
45 goes into 420 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 957075.9
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 957075.93
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
150 divided by 45 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 957075.933
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 957075.933 with a remainder of 0.0015.
