90578996 ÷ 824 
The aim is to understand the frequency of 824 in 90578996.

On to step 1:
824 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 824

Moving on to step 2:
824 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 824

Going ahead to step 3:
When dividing 905 by 824, we get 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 824 from 905 to get 81.
Take the next digit (7) from the dividend and append it to 81, then repeat: 817 / 824

Let's proceed to step 4:
824 goes into 817 0 times with a remainder of 817.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 817, we end up with 817.
Take the next digit (8) from the dividend and append it to 817, then repeat: 8178 / 824

Moving on to step 5:
824 can be fit into 8178 9 times, resulting in a remainder of 762.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we subtract 7416 from 8178, we get 762.
Grab the next digit (9) from the dividend, add it to 762, then carry on: 7629 / 824

Advancing to step 6:
The number 824 fits into 7629 9 times, leaving a remainder of 213.
The next digit of our result is 9. 
Result so far: 1099.0
Subtracting 7416 from 7629 leaves us with 213.
Fetch the next digit (9) from the dividend, attach it to 213 and continue: 2139 / 824

Going ahead to step 7:
If we divide 2139 by 824, we get 2 and a remainder of 491.
The next digit of our result is 2. 
Result so far: 10992.0
Subtract 1648 from 2139 to get 491.
Append the next digit (6) from the dividend to 491 and continue with: 4916 / 824

Let's proceed to step 8:
If we divide 4916 by 824, we get 5 and a remainder of 796.
Put 5 as the next digit of the answer. 
Result so far: 109925.0
Subtracting 4120 from 4916 leaves us with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

On to step 9:
If we divide 7960 by 824, we get 9 and a remainder of 544.
Write down 9 as next digit of the result. 
Result so far: 109925.9
If we take 7416 away from 7960, we end up 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.

Moving on to step 10:
When dividing 5440 by 824, we get 6 with a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 109925.96
The remainder is 496 after subtracting 4944 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 11:
The number 824 fits into 4960 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 109925.966
Subtracting 4944 from 4960 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 109925.966 with a remainder of 0.0016.
