Let's divide 386490 by 24
The aim is to understand the frequency of 24 in 386490.

Advancing to step 1:
When dividing 3 by 24, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 24

Let's proceed to step 2:
24 can be fit into 38 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 14 after subtracting 24 from 38.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 24

Step 3:
24 goes into 146 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 144 from 146 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 24

Going ahead to step 4:
24 can be fit into 24 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 161.0
The remainder is 0 after subtracting 24 from 24.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 24

Let's proceed to step 5:
When dividing 9 by 24, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 1610.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 24

On to step 6:
If we divide 90 by 24, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 16103.0
If we subtract 72 from 90, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
24 goes into 180 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 16103.7
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
120 divided by 24 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 16103.75
Subtract 120 from 120 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.

Moving on to step 9:
0 divided by 24 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16103.75
Deduct 0 from 0 and we're left 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 10:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16103.75
If we subtract 0 from 0, we 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.

The final result is 16103.75 with a remainder of 0.0.
