384590 divided by 45 
The aim is to understand the frequency of 45 in 384590.

Moving on to step 1:
45 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 45

Going ahead to step 2:
When dividing 38 by 45, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 45

Step 3:
If we divide 384 by 45, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 360 from 384, we get 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 45

Going ahead to step 4:
When dividing 245 by 45, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 85.0
Subtract 225 from 245 to get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 45

Step 5:
The number 45 fits into 209 4 times, leaving a remainder of 29.
The next digit of our result is 4. 
Result so far: 854.0
If we subtract 180 from 209, we get 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 45

Moving on to step 6:
If we divide 290 by 45, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 8546.0
The remainder is 20 after subtracting 270 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
If we divide 200 by 45, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 8546.4
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 8546.44
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 8546.44 with a remaining 0.02.
