We look at the division of 809193 by 10 
Let's see how many times 10 fits into 809193.

Step 1:
8 divided by 10 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 10

Let's proceed to step 2:
The number 10 fits into 80 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 80 from 80, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 10

On to step 3:
10 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 10

Let's proceed to step 4:
If we divide 91 by 10, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 809.0
If we take 90 away from 91, we end up with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 10

Step 5:
The number 10 fits into 19 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 8091.0
Deduct 10 from 19 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 10

Moving on to step 6:
93 divided by 10 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 80919.0
If we subtract 90 from 93, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 10 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 80919.3
If we take 30 away from 30, 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.

Moving on to step 8:
10 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: 80919.3
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.

On to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 80919.3
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.

Our division results in 80919.3 with a remaining 0.0.
