We're dividing 17004975 by 809 
Our goal is to divide 17004975 by 809.

Let's proceed to step 1:
1 divided by 809 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 809

Moving on to step 2:
When dividing 17 by 809, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 809

Moving on to step 3:
The number 809 fits into 170 0 times, leaving a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 170 after subtracting 0 from 170.
Grab the next digit (0) from the dividend, add it to 170, then carry on: 1700 / 809

Moving on to step 4:
1700 divided by 809 is 2 with a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1618 away from 1700, we end up with 82.
Fetch the next digit (4) from the dividend, attach it to 82 and continue: 824 / 809

Going ahead to step 5:
809 goes into 824 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 809 away from 824, we end up with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 809

Advancing to step 6:
809 goes into 159 0 times with a remainder of 159.
The next digit of our result is 0. 
Result so far: 210.0
Subtract 0 from 159 to get 159.
Fetch the next digit (7) from the dividend, attach it to 159 and continue: 1597 / 809

Going ahead to step 7:
When dividing 1597 by 809, we get 1 with a remainder of 788.
Write down 1 as next digit of the result. 
Result so far: 2101.0
Subtract 809 from 1597 to get 788.
Include the next digit (5) from the dividend after 788, then repeat: 7885 / 809

Moving on to step 8:
When dividing 7885 by 809, we get 9 with a remainder of 604.
The number 9 becomes the next digit in our result. 
Result so far: 21019.0
The remainder is 604 after subtracting 7281 from 7885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 9:
809 can be fit into 6040 7 times, resulting in a remainder of 377.
Use 7 as the next digit of our solution. 
Result so far: 21019.7
The remainder is 377 after subtracting 5663 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

On to step 10:
If we divide 3770 by 809, we get 4 and a remainder of 534.
The next digit of our result is 4. 
Result so far: 21019.74
Subtract 3236 from 3770 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 11:
When dividing 5340 by 809, we get 6 with a remainder of 486.
Put 6 as the next digit of the answer. 
Result so far: 21019.746
Deduct 4854 from 5340 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 12:
When dividing 4860 by 809, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 21019.7466
If we take 4854 away from 4860, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 21019.7466 with a remainder of 6e-05.
