864002 divided by 4 
The aim is to understand the frequency of 4 in 864002.

On to step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 4

Moving on to step 2:
6 divided by 4 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 2 after subtracting 4 from 6.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 4

Step 3:
4 goes into 24 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
If we subtract 24 from 24, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Advancing to step 4:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2160.0
If we subtract 0 from 0, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 4

Let's proceed to step 5:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21600.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 4

Step 6:
4 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 216000.0
Subtracting 0 from 2 leaves us 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.

Moving on to step 7:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 216000.5
If we take 20 away from 20, we end up 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.

On to step 8:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 216000.5
Subtract 0 from 0 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.

Advancing to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 216000.5
If we take 0 away from 0, we end up 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.

After the division, we end up with 216000.5 and a remainder of 0.0.
