250568 divided by 45 
The aim is to understand the frequency of 45 in 250568.

Step 1:
45 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 45

Step 2:
If we divide 25 by 45, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 45

Advancing to step 3:
45 goes into 250 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 225 away from 250, we end up with 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 45

Advancing to step 4:
The number 45 fits into 255 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 55.0
If we subtract 225 from 255, we get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 45

Moving on to step 5:
306 divided by 45 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 556.0
Deduct 270 from 306 and we're left with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 45

On to step 6:
45 can be fit into 368 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 5568.0
The remainder is 8 after subtracting 360 from 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
If we divide 80 by 45, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 5568.1
If we take 45 away from 80, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
45 can be fit into 350 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 5568.17
Deduct 315 from 350 and we're left with 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:
45 can be fit into 350 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 5568.177
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 5568.177 with a remainder of 0.0035.
