878213 divided by 24 
The aim is to understand the frequency of 24 in 878213.

Let's proceed to step 1:
8 divided by 24 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
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

Going ahead to step 2:
The number 24 fits into 87 3 times, leaving 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.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 24

Advancing to step 3:
24 goes into 158 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 36.0
If we take 144 away from 158, we end up with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 24

Moving on to step 4:
24 can be fit into 142 5 times, resulting in a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 365.0
Subtracting 120 from 142 leaves us with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 24

On to step 5:
24 can be fit into 221 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 3659.0
Subtract 216 from 221 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 24

On to step 6:
24 goes into 53 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 36592.0
If we subtract 48 from 53, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 divided by 24 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 36592.2
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 24 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 36592.2
Deduct 0 from 20 and we're left with 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 9:
24 goes into 200 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 36592.208
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.

Step 10:
24 goes into 80 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 36592.2083
If we take 72 away from 80, we end up 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.

Going ahead to step 11:
24 goes into 80 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 36592.20833
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 final result is 36592.20833 with a remainder of 8e-06.
