We look at the division of 806389 by 10 
Our goal is to divide 806389 by 10.

Going ahead to step 1:
When dividing 8 by 10, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 10

Advancing to step 2:
10 can be fit into 80 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 80 from 80 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 10

Let's proceed to step 3:
The number 10 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 10

Let's proceed to step 4:
63 divided by 10 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 806.0
Deduct 60 from 63 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 10

Going ahead to step 5:
When dividing 38 by 10, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 8063.0
The remainder is 8 after subtracting 30 from 38.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 10

Step 6:
10 goes into 89 8 times with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 80638.0
If we subtract 80 from 89, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
10 goes into 90 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 80638.9
Deduct 90 from 90 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.

Let's proceed to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80638.9
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:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 80638.9
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.

Our division results in 80638.9 with a remaining 0.0.
