Let's divide 802309 by 4
Let's see how many times 4 fits into 802309.

Moving on to step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Step 2:
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: 20.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 4

On to step 3:
When dividing 2 by 4, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 200.0
Subtract 0 from 2 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 4

On to step 4:
4 can be fit into 23 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 2005.0
If we take 20 away from 23, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

Advancing to step 5:
30 divided by 4 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 20057.0
If we take 28 away from 30, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 4

Going ahead to step 6:
4 can be fit into 29 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 200577.0
Subtract 28 from 29 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.

Advancing to step 7:
When dividing 10 by 4, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 200577.2
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.

Step 8:
4 goes into 20 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 200577.25
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.

Advancing to step 9:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 200577.25
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.

Step 10:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 200577.25
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.

In conclusion, the division gives 200577.25 with a balance of 0.0.
