We look at the division of 812358 by 4 
Let's see how many times 4 fits into 812358.

Step 1:
8 divided by 4 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
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

Advancing to step 2:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 4

Advancing to step 3:
When dividing 12 by 4, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 203.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

On to step 4:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 2030.0
Subtract 0 from 3 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 4

Let's proceed to step 5:
If we divide 35 by 4, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 20308.0
Subtracting 32 from 35 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 4

Moving on to step 6:
When dividing 38 by 4, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 203089.0
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:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 203089.5
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.

Going ahead to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 203089.5
Deduct 0 from 0 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.

Going ahead to step 9:
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: 203089.5
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.

After the division, we end up with 203089.5 and a remainder of 0.0.
