45550264 ÷ 576 
The aim is to understand the frequency of 576 in 45550264.

Moving on to step 1:
When dividing 4 by 576, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 576

Advancing to step 2:
576 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 576

Step 3:
576 goes into 455 0 times with a remainder of 455.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 455 to get 455.
Take the next digit (5) from the dividend and append it to 455, then repeat: 4555 / 576

Step 4:
The number 576 fits into 4555 7 times, leaving a remainder of 523.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4032 from 4555, we get 523.
Append the next digit (0) from the dividend to 523 and continue with: 5230 / 576

Moving on to step 5:
576 goes into 5230 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 79.0
Subtracting 5184 from 5230 leaves us with 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 576

On to step 6:
If we divide 462 by 576, we get 0 and a remainder of 462.
The next digit of our result is 0. 
Result so far: 790.0
The remainder is 462 after subtracting 0 from 462.
Append the next digit (6) from the dividend to 462 and continue with: 4626 / 576

Let's proceed to step 7:
When dividing 4626 by 576, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 7908.0
If we take 4608 away from 4626, we end up with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 576

On to step 8:
576 can be fit into 184 0 times, resulting in a remainder of 184.
Write down 0 as next digit of the result. 
Result so far: 79080.0
Deduct 0 from 184 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 9:
576 goes into 1840 3 times with a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 79080.3
Subtract 1728 from 1840 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 10:
1120 divided by 576 is 1 with a remainder of 544.
Use 1 as the next digit of our solution. 
Result so far: 79080.31
Subtracting 576 from 1120 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 11:
576 goes into 5440 9 times with a remainder of 256.
The number 9 becomes the next digit in our result. 
Result so far: 79080.319
Subtracting 5184 from 5440 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 12:
2560 divided by 576 is 4 with a remainder of 256.
The next digit of our result is 4. 
Result so far: 79080.3194
The remainder is 256 after subtracting 2304 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 13:
When dividing 2560 by 576, we get 4 with a remainder of 256.
The next digit of our result is 4. 
Result so far: 79080.31944
If we subtract 2304 from 2560, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 79080.31944 and a remainder of 0.000256.
