809853 divided by 17 
Let's see how many times 17 fits into 809853.

Moving on to step 1:
17 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 17

Step 2:
When dividing 80 by 17, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 68 from 80, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 17

Moving on to step 3:
17 goes into 129 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 119 away from 129, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 17

Moving on to step 4:
17 can be fit into 108 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 476.0
Subtracting 102 from 108 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 17

Going ahead to step 5:
When dividing 65 by 17, we get 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 4763.0
If we take 51 away from 65, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 17

Step 6:
17 goes into 143 8 times with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 47638.0
Subtracting 136 from 143 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 17 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 47638.4
Subtracting 68 from 70 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 17 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 47638.41
If we subtract 17 from 20, 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.

On to step 9:
17 goes into 30 1 times with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 47638.411
If we subtract 17 from 30, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 47638.411 with a remainder of 0.0013.
