15806612 ÷ 809 
Let's see how many times 809 fits into 15806612.

Moving on to step 1:
1 divided by 809 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 809

Step 2:
809 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 809

Moving on to step 3:
The number 809 fits into 158 0 times, leaving a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 158 after subtracting 0 from 158.
Bring next digit (0) of the dividend behind the 158 and repeat the process: 1580 / 809

Step 4:
If we divide 1580 by 809, we get 1 and a remainder of 771.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 809 away from 1580, we end up with 771.
Grab the next digit (6) from the dividend, add it to 771, then carry on: 7716 / 809

Advancing to step 5:
809 goes into 7716 9 times with a remainder of 435.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 7281 from 7716 and we're left with 435.
Take the next digit (6) from the dividend and append it to 435, then repeat: 4356 / 809

Let's proceed to step 6:
If we divide 4356 by 809, we get 5 and a remainder of 311.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
If we subtract 4045 from 4356, we get 311.
Take the next digit (1) from the dividend and append it to 311, then repeat: 3111 / 809

Step 7:
The number 809 fits into 3111 3 times, leaving a remainder of 684.
Put 3 as the next digit of the answer. 
Result so far: 1953.0
Subtract 2427 from 3111 to get 684.
Bring next digit (2) of the dividend behind the 684 and repeat the process: 6842 / 809

Moving on to step 8:
809 goes into 6842 8 times with a remainder of 370.
The next digit of our result is 8. 
Result so far: 19538.0
If we take 6472 away from 6842, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 9:
The number 809 fits into 3700 4 times, leaving a remainder of 464.
The number 4 becomes the next digit in our result. 
Result so far: 19538.4
Subtract 3236 from 3700 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 10:
809 goes into 4640 5 times with a remainder of 595.
The next digit of our result is 5. 
Result so far: 19538.45
Subtract 4045 from 4640 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 11:
809 can be fit into 5950 7 times, resulting in a remainder of 287.
Record the quotient 7 as the next digit in the result. 
Result so far: 19538.457
Subtracting 5663 from 5950 leaves us with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 12:
The number 809 fits into 2870 3 times, leaving a remainder of 443.
Record the quotient 3 as the next digit in the result. 
Result so far: 19538.4573
The remainder is 443 after subtracting 2427 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Step 13:
The number 809 fits into 4430 5 times, leaving a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 19538.45735
If we take 4045 away from 4430, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 14:
3850 divided by 809 is 4 with a remainder of 614.
The number 4 becomes the next digit in our result. 
Result so far: 19538.457354
If we take 3236 away from 3850, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 15:
When dividing 6140 by 809, we get 7 with a remainder of 477.
Put 7 as the next digit of the answer. 
Result so far: 19538.4573547
Subtracting 5663 from 6140 leaves us with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Moving on to step 16:
The number 809 fits into 4770 5 times, leaving a remainder of 725.
The next digit of our result is 5. 
Result so far: 19538.45735475
Deduct 4045 from 4770 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

In conclusion, the division gives 19538.45735475 with a balance of 7.25e-07.
