We're dividing 2443400 by 864 
The aim is to understand the frequency of 864 in 2443400.

Moving on to step 1:
2 divided by 864 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 864

Let's proceed to step 2:
The number 864 fits into 24 0 times, leaving a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 864

Moving on to step 3:
244 divided by 864 is 0 with a remainder of 244.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 244 after subtracting 0 from 244.
Bring next digit (3) of the dividend behind the 244 and repeat the process: 2443 / 864

Moving on to step 4:
The number 864 fits into 2443 2 times, leaving a remainder of 715.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1728 from 2443 and we're left with 715.
Take the next digit (4) from the dividend and append it to 715, then repeat: 7154 / 864

Step 5:
7154 divided by 864 is 8 with a remainder of 242.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 6912 away from 7154, we end up with 242.
Append the next digit (0) from the dividend to 242 and continue with: 2420 / 864

Moving on to step 6:
The number 864 fits into 2420 2 times, leaving a remainder of 692.
Put 2 as the next digit of the answer. 
Result so far: 282.0
The remainder is 692 after subtracting 1728 from 2420.
Bring next digit (0) of the dividend behind the 692 and repeat the process: 6920 / 864

On to step 7:
When dividing 6920 by 864, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 2828.0
The remainder is 8 after subtracting 6912 from 6920.
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 8:
If we divide 80 by 864, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 2828.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
864 goes into 800 0 times with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 2828.0
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final result is 2828.0 with a remainder of 0.8.
