803401 ÷ 4 
Our goal is to divide 803401 by 4.

Going ahead to step 1:
When dividing 8 by 4, we get 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 (0) from the dividend after 0, then repeat: 0 / 4

Let's proceed to step 2:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 0, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 4

Moving on to step 3:
The number 4 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 4

Going ahead to step 4:
4 can be fit into 34 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 2008.0
Subtracting 32 from 34 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Moving on to step 5:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 20085.0
The remainder is 0 after subtracting 20 from 20.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 4

On to step 6:
4 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 200850.0
If we subtract 0 from 1, we 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.

Moving on to step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 200850.2
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.

On to step 8:
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: 200850.25
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.

Advancing to step 9:
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: 200850.25
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.

Moving on to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 200850.25
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.

The quotient of the division is 200850.25, and the remainder is 0.0.
