We're dividing 784221 by 4 
The aim is to understand the frequency of 4 in 784221.

Let's proceed to step 1:
If we divide 7 by 4, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 4 away from 7, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 4

Let's proceed to step 2:
4 can be fit into 38 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 2 after subtracting 36 from 38.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 4

Going ahead to step 3:
The number 4 fits into 24 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
The remainder is 0 after subtracting 24 from 24.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 4

Step 4:
When dividing 2 by 4, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 1960.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 4

Step 5:
22 divided by 4 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 19605.0
Subtracting 20 from 22 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

On to step 6:
The number 4 fits into 21 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 196055.0
Deduct 20 from 21 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 4, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 196055.2
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 4 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 196055.25
Subtract 20 from 20 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:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 196055.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 196055.25
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.

In conclusion, the division gives 196055.25 with a balance of 0.0.
