We're dividing 21686706 by 809 
We want to divide 21686706 by 809.

Let's proceed to step 1:
809 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 809

Let's proceed to step 2:
21 divided by 809 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 809

Moving on to step 3:
216 divided by 809 is 0 with a remainder of 216.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 216, we get 216.
Grab the next digit (8) from the dividend, add it to 216, then carry on: 2168 / 809

Let's proceed to step 4:
809 goes into 2168 2 times with a remainder of 550.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1618 from 2168, we get 550.
Include the next digit (6) from the dividend after 550, then repeat: 5506 / 809

Going ahead to step 5:
When dividing 5506 by 809, we get 6 with a remainder of 652.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 4854 from 5506 leaves us with 652.
Take the next digit (7) from the dividend and append it to 652, then repeat: 6527 / 809

Let's proceed to step 6:
809 goes into 6527 8 times with a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 268.0
If we subtract 6472 from 6527, we get 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 809

Going ahead to step 7:
809 goes into 550 0 times with a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 2680.0
Deduct 0 from 550 and we're left with 550.
Take the next digit (6) from the dividend and append it to 550, then repeat: 5506 / 809

Let's proceed to step 8:
If we divide 5506 by 809, we get 6 and a remainder of 652.
The next digit of our result is 6. 
Result so far: 26806.0
If we take 4854 away from 5506, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 9:
809 goes into 6520 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 26806.8
If we take 6472 away from 6520, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
480 divided by 809 is 0 with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 26806.8
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 11:
When dividing 4800 by 809, we get 5 with a remainder of 755.
Write down 5 as next digit of the result. 
Result so far: 26806.805
If we take 4045 away from 4800, we end up with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

On to step 12:
The number 809 fits into 7550 9 times, leaving a remainder of 269.
The number 9 becomes the next digit in our result. 
Result so far: 26806.8059
Deduct 7281 from 7550 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 13:
The number 809 fits into 2690 3 times, leaving a remainder of 263.
The number 3 becomes the next digit in our result. 
Result so far: 26806.80593
If we take 2427 away from 2690, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 14:
809 goes into 2630 3 times with a remainder of 203.
Use 3 as the next digit of our solution. 
Result so far: 26806.805933
If we take 2427 away from 2630, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

The final outcome is 26806.805933, with a leftover of 2.03e-05.
