22690646 ÷ 809 
We want to divide 22690646 by 809.

Advancing to step 1:
If we divide 2 by 809, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 809

Let's proceed to step 2:
When dividing 22 by 809, we get 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 809

Step 3:
If we divide 226 by 809, we get 0 and a remainder of 226.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 226, we end up with 226.
Append the next digit (9) from the dividend to 226 and continue with: 2269 / 809

Going ahead to step 4:
809 can be fit into 2269 2 times, resulting in a remainder of 651.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1618 from 2269, we get 651.
Include the next digit (0) from the dividend after 651, then repeat: 6510 / 809

Moving on to step 5:
809 goes into 6510 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 38 after subtracting 6472 from 6510.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 809

On to step 6:
809 can be fit into 386 0 times, resulting in a remainder of 386.
Put 0 as the next digit of the answer. 
Result so far: 280.0
The remainder is 386 after subtracting 0 from 386.
Include the next digit (4) from the dividend after 386, then repeat: 3864 / 809

Advancing to step 7:
If we divide 3864 by 809, we get 4 and a remainder of 628.
Use 4 as the next digit of our solution. 
Result so far: 2804.0
Deduct 3236 from 3864 and we're left with 628.
Bring next digit (6) of the dividend behind the 628 and repeat the process: 6286 / 809

Advancing to step 8:
809 can be fit into 6286 7 times, resulting in a remainder of 623.
Put 7 as the next digit of the answer. 
Result so far: 28047.0
The remainder is 623 after subtracting 5663 from 6286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Going ahead to step 9:
809 can be fit into 6230 7 times, resulting in a remainder of 567.
Write down 7 as next digit of the result. 
Result so far: 28047.7
Subtract 5663 from 6230 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Advancing to step 10:
809 goes into 5670 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 28047.77
Subtracting 5663 from 5670 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.

After the division, we end up with 28047.77 and a remainder of 0.007.
