We look at the division of 812480 by 4 
Our goal is to divide 812480 by 4.

On to step 1:
8 divided by 4 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 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
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 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
The remainder is 0 after subtracting 12 from 12.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 4

Let's proceed to step 4:
4 goes into 4 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 2031.0
Subtract 4 from 4 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 4

Let's proceed to step 5:
If we divide 8 by 4, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 20312.0
Subtract 8 from 8 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Let's proceed to step 6:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 203120.0
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.

On to step 7:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 203120.0
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.

On to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 203120.0
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.

The final result is 203120.0 with a remainder of 0.0.
