We look at the division of 412761 by 45 
The aim is to understand the frequency of 45 in 412761.

Moving on to step 1:
4 divided by 45 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 45

Step 2:
41 divided by 45 is 0 with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 45

Moving on to step 3:
412 divided by 45 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 405 from 412 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 45

Step 4:
When dividing 77 by 45, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtracting 45 from 77 leaves us with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 45

Moving on to step 5:
45 can be fit into 326 7 times, resulting in a remainder of 11.
The next digit of our result is 7. 
Result so far: 917.0
Subtract 315 from 326 to get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 45

Advancing to step 6:
111 divided by 45 is 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 9172.0
If we subtract 90 from 111, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
The number 45 fits into 210 4 times, leaving a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 9172.4
Subtracting 180 from 210 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 9172.46
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
If we divide 300 by 45, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 9172.466
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 9172.466 with a remaining 0.003.
