We look at the division of 15164753 by 809 
We want to figure out the number of times 15164753 can be divided by 809.

Going ahead to step 1:
809 can be fit into 1 0 times, resulting in 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.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 809

Advancing to step 2:
If we divide 15 by 809, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 809

Let's proceed to step 3:
If we divide 151 by 809, we get 0 and a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 151 and we're left with 151.
Append the next digit (6) from the dividend to 151 and continue with: 1516 / 809

Moving on to step 4:
When dividing 1516 by 809, we get 1 with a remainder of 707.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 809 from 1516 leaves us with 707.
Append the next digit (4) from the dividend to 707 and continue with: 7074 / 809

On to step 5:
The number 809 fits into 7074 8 times, leaving a remainder of 602.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 6472 from 7074 leaves us with 602.
Bring next digit (7) of the dividend behind the 602 and repeat the process: 6027 / 809

Advancing to step 6:
809 can be fit into 6027 7 times, resulting in a remainder of 364.
Write down 7 as next digit of the result. 
Result so far: 187.0
Subtract 5663 from 6027 to get 364.
Take the next digit (5) from the dividend and append it to 364, then repeat: 3645 / 809

On to step 7:
809 can be fit into 3645 4 times, resulting in a remainder of 409.
Put 4 as the next digit of the answer. 
Result so far: 1874.0
Subtract 3236 from 3645 to get 409.
Bring next digit (3) of the dividend behind the 409 and repeat the process: 4093 / 809

On to step 8:
If we divide 4093 by 809, we get 5 and a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 18745.0
Deduct 4045 from 4093 and we're left 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.

Going ahead to step 9:
480 divided by 809 is 0 with a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 18745.0
The remainder is 480 after subtracting 0 from 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 10:
4800 divided by 809 is 5 with a remainder of 755.
Put 5 as the next digit of the answer. 
Result so far: 18745.05
Subtract 4045 from 4800 to get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Advancing to step 11:
809 can be fit into 7550 9 times, resulting in a remainder of 269.
The next digit of our result is 9. 
Result so far: 18745.059
If we subtract 7281 from 7550, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 12:
809 goes into 2690 3 times with a remainder of 263.
The number 3 becomes the next digit in our result. 
Result so far: 18745.0593
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.

Advancing to step 13:
The number 809 fits into 2630 3 times, leaving a remainder of 203.
Put 3 as the next digit of the answer. 
Result so far: 18745.05933
Deduct 2427 from 2630 and we're left 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.

Our division results in 18745.05933 with a remaining 0.000203.
