Let's divide 818890 by 4
We want to divide 818890 by 4.

Moving on to step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 8 from 8 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 4

Step 2:
1 divided by 4 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 4

Going ahead to step 3:
4 can be fit into 18 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 204.0
If we take 16 away from 18, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 4

Step 4:
If we divide 28 by 4, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 2047.0
If we subtract 28 from 28, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 4

On to step 5:
If we divide 9 by 4, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 20472.0
Subtracting 8 from 9 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 4

Going ahead to step 6:
4 goes into 10 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 204722.0
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 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 204722.5
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.

On to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 204722.5
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.

Going ahead to step 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 204722.5
If we take 0 away from 0, 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.

The final result is 204722.5 with a remainder of 0.0.
