15671849 ÷ 24 
The aim is to understand the frequency of 24 in 15671849.

On to step 1:
24 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 24

On to step 2:
The number 24 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 24

Advancing to step 3:
24 can be fit into 156 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 12 after subtracting 144 from 156.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 24

Advancing to step 4:
When dividing 127 by 24, we get 5 with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 65.0
If we subtract 120 from 127, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 24

Moving on to step 5:
71 divided by 24 is 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 652.0
Subtracting 48 from 71 leaves us with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 24

Going ahead to step 6:
238 divided by 24 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 6529.0
Deduct 216 from 238 and we're left with 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 24

On to step 7:
224 divided by 24 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 65299.0
If we subtract 216 from 224, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 24

Moving on to step 8:
24 can be fit into 89 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 652993.0
If we take 72 away from 89, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 24 fits into 170 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 652993.7
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 24, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 652993.7
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
24 goes into 200 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 652993.708
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
When dividing 80 by 24, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 652993.7083
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
24 can be fit into 80 3 times, resulting in a remainder of 8.
The next digit of our result is 3. 
Result so far: 652993.70833
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 652993.70833 and a remainder of 8e-06.
