We look at the division of 686287 by 24 
The aim is to understand the frequency of 24 in 686287.

Going ahead to step 1:
6 divided by 24 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 24

Moving on to step 2:
24 goes into 68 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 20 after subtracting 48 from 68.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 24

Going ahead to step 3:
206 divided by 24 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 192 from 206 to get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 24

Step 4:
When dividing 142 by 24, we get 5 with a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 285.0
Subtract 120 from 142 to get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 24

Step 5:
When dividing 228 by 24, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 2859.0
Deduct 216 from 228 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 24

Let's proceed to step 6:
127 divided by 24 is 5 with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 28595.0
If we take 120 away from 127, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 24, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 28595.2
The remainder is 22 after subtracting 48 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
The number 24 fits into 220 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 28595.29
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 24 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 28595.291
If we subtract 24 from 40, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 24 fits into 160 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 28595.2916
If we take 144 away from 160, we end up 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.

Going ahead to step 11:
If we divide 160 by 24, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 28595.29166
If we take 144 away from 160, we end up 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.

Our division results in 28595.29166 with a remaining 1.6e-05.
