We look at the division of 812793 by 4 
We're looking to find how many times 4 goes into 812793.

Advancing to step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 4

Step 2:
When dividing 1 by 4, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 4

On to step 3:
12 divided by 4 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 203.0
If we take 12 away from 12, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 4

On to step 4:
When dividing 7 by 4, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 2031.0
Subtracting 4 from 7 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 4

Moving on to step 5:
4 can be fit into 39 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 20319.0
Subtract 36 from 39 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Advancing to step 6:
When dividing 33 by 4, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 203198.0
If we take 32 away from 33, 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.

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: 203198.2
If we subtract 8 from 10, we 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.

Step 8:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 203198.25
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.

Advancing to step 9:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 203198.25
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.

Moving on to step 10:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 203198.25
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 quotient of the division is 203198.25, and the remainder is 0.0.
