447583 divided by 45 
The aim is to understand the frequency of 45 in 447583.

Step 1:
When dividing 4 by 45, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 45

Let's proceed to step 2:
45 goes into 44 0 times with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 45

Step 3:
45 goes into 447 9 times with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 405 from 447 leaves us with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 45

Advancing to step 4:
The number 45 fits into 425 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Deduct 405 from 425 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 45

Advancing to step 5:
The number 45 fits into 208 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 994.0
Deduct 180 from 208 and we're left with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 45

Let's proceed to step 6:
45 goes into 283 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 9946.0
If we subtract 270 from 283, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 45, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 9946.2
Deduct 90 from 130 and we're left 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.

Moving on to step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 9946.28
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.

Step 9:
If we divide 400 by 45, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 9946.288
Deduct 360 from 400 and we're left 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.

The final result is 9946.288 with a remainder of 0.004.
