We're dividing 87129395 by 24 
The aim is to understand the frequency of 24 in 87129395.

Let's proceed to step 1:
8 divided by 24 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 24

Step 2:
When dividing 87 by 24, we get 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 72 from 87 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 24

Going ahead to step 3:
The number 24 fits into 151 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 7 after subtracting 144 from 151.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 24

On to step 4:
If we divide 72 by 24, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 363.0
Subtract 72 from 72 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 24

Going ahead to step 5:
If we divide 9 by 24, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 3630.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 24

On to step 6:
24 goes into 93 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 36303.0
If we subtract 72 from 93, we get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 24

Let's proceed to step 7:
When dividing 219 by 24, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 363039.0
If we take 216 away from 219, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 24

Going ahead to step 8:
If we divide 35 by 24, we get 1 and a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 3630391.0
If we take 24 away from 35, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
If we divide 110 by 24, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 3630391.4
If we subtract 96 from 110, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
24 can be fit into 140 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 3630391.45
Subtract 120 from 140 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
24 goes into 200 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 3630391.458
Subtract 192 from 200 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
24 goes into 80 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3630391.4583
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
80 divided by 24 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3630391.45833
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 3630391.45833, and the remainder is 8e-06.
