We look at the division of 320510 by 4 
The aim is to understand the frequency of 4 in 320510.

Step 1:
4 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 4

On to step 2:
When dividing 32 by 4, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 32 from 32, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

On to step 3:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 4

Let's proceed to step 4:
The number 4 fits into 5 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 801.0
Subtracting 4 from 5 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Advancing to step 5:
11 divided by 4 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 8012.0
Subtract 8 from 11 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

On to step 6:
When dividing 30 by 4, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 80127.0
Deduct 28 from 30 and we're left 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.

Step 7:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 80127.5
If we subtract 20 from 20, 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.

Let's proceed to step 8:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80127.5
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.

Moving on to step 9:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 80127.5
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.

The quotient of the division is 80127.5, and the remainder is 0.0.
