90025 ÷ 4 
The aim is to understand the frequency of 4 in 90025.

Step 1:
4 goes into 9 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 8 from 9, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

Going ahead to step 2:
When dividing 10 by 4, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 8 from 10 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

On to step 3:
4 goes into 20 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 225.0
The remainder is 0 after subtracting 20 from 20.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 4

Advancing to step 4:
4 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 2250.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 4

On to step 5:
If we divide 25 by 4, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 22506.0
Subtract 24 from 25 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
10 divided by 4 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22506.2
Deduct 8 from 10 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 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 22506.25
The remainder is 0 after subtracting 20 from 20.
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 22506.25
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.

Let's proceed to step 9:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22506.25
Subtracting 0 from 0 leaves us 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 22506.25, and the remainder is 0.0.
