We divide 518470 by 45
The aim is to understand the frequency of 45 in 518470.

Going ahead to step 1:
45 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 45

Let's proceed to step 2:
If we divide 51 by 45, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 51 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 45

Moving on to step 3:
If we divide 68 by 45, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 45 from 68, we get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 45

Going ahead to step 4:
The number 45 fits into 234 5 times, leaving a remainder of 9.
The next digit of our result is 5. 
Result so far: 115.0
Deduct 225 from 234 and we're left with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 45

Moving on to step 5:
45 can be fit into 97 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 1152.0
If we subtract 90 from 97, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 45

Advancing to step 6:
45 can be fit into 70 1 times, resulting in a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 11521.0
Subtracting 45 from 70 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11521.5
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 11521.55
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 11521.55 with a remaining 0.025.
