We're dividing 481072 by 45 
The aim is to understand the frequency of 45 in 481072.

Step 1:
4 divided by 45 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 45

Going ahead to step 2:
45 goes into 48 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 48 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 45

Let's proceed to step 3:
45 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 45

Let's proceed to step 4:
310 divided by 45 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 106.0
If we take 270 away from 310, we end up with 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 45

Going ahead to step 5:
407 divided by 45 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1069.0
Deduct 405 from 407 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 45

Let's proceed to step 6:
When dividing 22 by 45, we get 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 10690.0
Subtract 0 from 22 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
The number 45 fits into 220 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 10690.4
Subtracting 180 from 220 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 10690.48
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
45 goes into 400 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 10690.488
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 10690.488 with a remaining 0.004.
