We're dividing 818589 by 4 
Let's see how many times 4 fits into 818589.

Let's proceed to step 1:
8 divided by 4 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 4

Going ahead to step 2:
When dividing 1 by 4, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 4

Advancing to step 3:
4 goes into 18 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
Subtract 16 from 18 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 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: 2046.0
Subtracting 24 from 25 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 4

Going ahead to step 5:
The number 4 fits into 18 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 20464.0
If we take 16 away from 18, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 4

Advancing to step 6:
29 divided by 4 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 204647.0
If we take 28 away from 29, we end up 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.

Moving on to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 204647.2
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.

Let's proceed to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 204647.25
If we take 20 away from 20, 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:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 204647.25
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.

Going ahead to step 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 204647.25
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.

Our division results in 204647.25 with a remaining 0.0.
