888609 ÷ 4 
The aim is to understand the frequency of 4 in 888609.

On to step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

Moving on to step 2:
If we divide 8 by 4, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 8 from 8 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 4

Advancing to step 3:
4 can be fit into 8 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
If we take 8 away from 8, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 4

Advancing to step 4:
If we divide 6 by 4, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 2221.0
If we subtract 4 from 6, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 4

Advancing to step 5:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 22215.0
Deduct 20 from 20 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 4

On to step 6:
4 can be fit into 9 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 222152.0
Subtracting 8 from 9 leaves us 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.

Advancing to step 7:
4 goes into 10 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 222152.2
The remainder is 2 after subtracting 8 from 10.
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 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 222152.25
Subtracting 20 from 20 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.

On to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 222152.25
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.

Let's proceed to step 10:
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: 222152.25
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.

In conclusion, the division gives 222152.25 with a balance of 0.0.
