We're dividing 915518 by 4 
The aim is to understand the frequency of 4 in 915518.

Advancing to step 1:
If we divide 9 by 4, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 8 from 9 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 4

Step 2:
11 divided by 4 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 8 away from 11, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 4

Let's proceed to step 3:
When dividing 35 by 4, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 228.0
Deduct 32 from 35 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 4

Step 4:
35 divided by 4 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 2288.0
Subtracting 32 from 35 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 4

Going ahead to step 5:
4 can be fit into 31 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 22887.0
Subtracting 28 from 31 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

Let's proceed to step 6:
4 goes into 38 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 228879.0
Subtract 36 from 38 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 228879.5
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: 228879.5
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.

Going ahead to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 228879.5
Subtract 0 from 0 to 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 228879.5, with a leftover of 0.0.
