809586 ÷ 4 
The aim is to understand the frequency of 4 in 809586.

On to step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Let's proceed to step 2:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

Let's proceed to step 3:
4 goes into 9 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 202.0
Subtract 8 from 9 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 4

Moving on to step 4:
If we divide 15 by 4, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 2023.0
Subtract 12 from 15 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 4

Moving on to step 5:
4 goes into 38 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 20239.0
The remainder is 2 after subtracting 36 from 38.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Going ahead to step 6:
The number 4 fits into 26 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 202396.0
If we take 24 away from 26, we end up 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.

Going ahead to step 7:
If we divide 20 by 4, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 202396.5
Deduct 20 from 20 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 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 202396.5
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.

Moving on to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 202396.5
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 outcome is 202396.5, with a leftover of 0.0.
