146586 divided by 4 
The aim is to understand the frequency of 4 in 146586.

Moving on to step 1:
If we divide 1 by 4, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 4

Going ahead to step 2:
14 divided by 4 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 12 from 14 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 4

Moving on to step 3:
4 can be fit into 26 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtract 24 from 26 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 4

Step 4:
When dividing 25 by 4, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 366.0
If we subtract 24 from 25, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

Moving on to step 5:
4 can be fit into 18 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 3664.0
If we take 16 away from 18, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 4

Moving on to step 6:
The number 4 fits into 26 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 36646.0
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.

Let's proceed to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 36646.5
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.

On to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36646.5
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.

Step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36646.5
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.

Our division results in 36646.5 with a remaining 0.0.
