We look at the division of 4511254 by 824 
The aim is to understand the frequency of 824 in 4511254.

Step 1:
If we divide 4 by 824, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 824

Advancing to step 2:
When dividing 45 by 824, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 824

Step 3:
When dividing 451 by 824, we get 0 with a remainder of 451.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 451 leaves us with 451.
Take the next digit (1) from the dividend and append it to 451, then repeat: 4511 / 824

Moving on to step 4:
4511 divided by 824 is 5 with a remainder of 391.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 4120 from 4511 to get 391.
Include the next digit (2) from the dividend after 391, then repeat: 3912 / 824

Step 5:
824 can be fit into 3912 4 times, resulting in a remainder of 616.
Use 4 as the next digit of our solution. 
Result so far: 54.0
The remainder is 616 after subtracting 3296 from 3912.
Grab the next digit (5) from the dividend, add it to 616, then carry on: 6165 / 824

Going ahead to step 6:
6165 divided by 824 is 7 with a remainder of 397.
The number 7 becomes the next digit in our result. 
Result so far: 547.0
If we take 5768 away from 6165, we end up with 397.
Append the next digit (4) from the dividend to 397 and continue with: 3974 / 824

Advancing to step 7:
The number 824 fits into 3974 4 times, leaving a remainder of 678.
Write down 4 as next digit of the result. 
Result so far: 5474.0
The remainder is 678 after subtracting 3296 from 3974.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 8:
6780 divided by 824 is 8 with a remainder of 188.
Use 8 as the next digit of our solution. 
Result so far: 5474.8
If we take 6592 away from 6780, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 9:
When dividing 1880 by 824, we get 2 with a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 5474.82
Subtract 1648 from 1880 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 10:
2320 divided by 824 is 2 with a remainder of 672.
Put 2 as the next digit of the answer. 
Result so far: 5474.822
Subtract 1648 from 2320 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The quotient of the division is 5474.822, and the remainder is 0.0672.
