We're dividing 382949 by 45 
The aim is to understand the frequency of 45 in 382949.

Step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 45

Step 2:
38 divided by 45 is 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 45

Going ahead to step 3:
45 goes into 382 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 360 away from 382, we end up with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 45

Advancing to step 4:
229 divided by 45 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 225 from 229, we get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 45

On to step 5:
When dividing 44 by 45, we get 0 with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
Subtract 0 from 44 to get 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 45

On to step 6:
The number 45 fits into 449 9 times, leaving a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 8509.0
If we subtract 405 from 449, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
The number 45 fits into 440 9 times, leaving a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 8509.9
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
If we divide 350 by 45, we get 7 and a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 8509.97
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
When dividing 350 by 45, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 8509.977
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 8509.977 with a remainder of 0.0035.
