810491 ÷ 10 
Our goal is to divide 810491 by 10.

Advancing to step 1:
10 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 10

Advancing to step 2:
If we divide 81 by 10, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 80 from 81, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 10

Let's proceed to step 3:
10 can be fit into 10 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 0 after subtracting 10 from 10.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 10

Moving on to step 4:
The number 10 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 810.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 10

On to step 5:
10 can be fit into 49 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 8104.0
Deduct 40 from 49 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 10

Let's proceed to step 6:
If we divide 91 by 10, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 81049.0
If we subtract 90 from 91, 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.

On to step 7:
10 can be fit into 10 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 81049.1
Subtract 10 from 10 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:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 81049.1
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.

Going ahead to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 81049.1
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.

After the division, we end up with 81049.1 and a remainder of 0.0.
