We look at the division of 15385046 by 809 
We want to divide 15385046 by 809.

On to step 1:
1 divided by 809 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 809

Moving on to step 2:
The number 809 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 809

On to step 3:
The number 809 fits into 153 0 times, leaving a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 153 and we're left with 153.
Bring next digit (8) of the dividend behind the 153 and repeat the process: 1538 / 809

Moving on to step 4:
The number 809 fits into 1538 1 times, leaving a remainder of 729.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 809 from 1538 and we're left with 729.
Fetch the next digit (5) from the dividend, attach it to 729 and continue: 7295 / 809

On to step 5:
The number 809 fits into 7295 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 14 after subtracting 7281 from 7295.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 809

Advancing to step 6:
If we divide 140 by 809, we get 0 and a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 190.0
If we take 0 away from 140, we end up with 140.
Fetch the next digit (4) from the dividend, attach it to 140 and continue: 1404 / 809

On to step 7:
When dividing 1404 by 809, we get 1 with a remainder of 595.
The next digit of our result is 1. 
Result so far: 1901.0
Subtracting 809 from 1404 leaves us with 595.
Fetch the next digit (6) from the dividend, attach it to 595 and continue: 5956 / 809

Step 8:
809 can be fit into 5956 7 times, resulting in a remainder of 293.
Put 7 as the next digit of the answer. 
Result so far: 19017.0
Subtract 5663 from 5956 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 9:
If we divide 2930 by 809, we get 3 and a remainder of 503.
The next digit of our result is 3. 
Result so far: 19017.3
Subtract 2427 from 2930 to get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Let's proceed to step 10:
809 can be fit into 5030 6 times, resulting in a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 19017.36
Subtract 4854 from 5030 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 11:
When dividing 1760 by 809, we get 2 with a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 19017.362
Subtract 1618 from 1760 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 12:
809 goes into 1420 1 times with a remainder of 611.
Use 1 as the next digit of our solution. 
Result so far: 19017.3621
If we take 809 away from 1420, we end up with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Going ahead to step 13:
When dividing 6110 by 809, we get 7 with a remainder of 447.
The number 7 becomes the next digit in our result. 
Result so far: 19017.36217
Subtract 5663 from 6110 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Let's proceed to step 14:
809 can be fit into 4470 5 times, resulting in a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 19017.362175
Subtract 4045 from 4470 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 15:
The number 809 fits into 4250 5 times, leaving a remainder of 205.
The next digit of our result is 5. 
Result so far: 19017.3621755
Subtract 4045 from 4250 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 19017.3621755 and a remainder of 2.05e-06.
