We divide 990144 by 24
The aim is to understand the frequency of 24 in 990144.

Advancing to step 1:
When dividing 9 by 24, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 24

Going ahead to step 2:
The number 24 fits into 99 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 96 from 99 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 24

Advancing to step 3:
30 divided by 24 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we take 24 away from 30, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 24

On to step 4:
If we divide 61 by 24, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 412.0
Subtract 48 from 61 to get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 24

On to step 5:
The number 24 fits into 134 5 times, leaving a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 4125.0
Deduct 120 from 134 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 24

Step 6:
24 goes into 144 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 41256.0
Subtracting 144 from 144 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
24 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41256.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 24, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 41256.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 41256.0, and the remainder is 0.0.
