Let's divide 816510 by 4
We're looking to find how many times 4 goes into 816510.

Let's proceed to 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
If we subtract 8 from 8, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

On to step 2:
When dividing 1 by 4, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 4

On to step 3:
4 goes into 16 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 204.0
If we subtract 16 from 16, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 4

Advancing to step 4:
4 can be fit into 5 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 2041.0
If we take 4 away from 5, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

On to step 5:
When dividing 11 by 4, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 20412.0
Deduct 8 from 11 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

Going ahead to step 6:
The number 4 fits into 30 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 204127.0
Subtract 28 from 30 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.

Step 7:
20 divided by 4 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 204127.5
Subtract 20 from 20 to 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.

Moving on to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 204127.5
Subtract 0 from 0 to 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.

Moving on to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 204127.5
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.

The quotient of the division is 204127.5, and the remainder is 0.0.
