We look at the division of 86386065 by 809 
We want to divide 86386065 by 809.

Step 1:
When dividing 8 by 809, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 809

Going ahead to step 2:
When dividing 86 by 809, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 809

Let's proceed to step 3:
863 divided by 809 is 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 809 from 863 to get 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 809

Going ahead to step 4:
When dividing 548 by 809, we get 0 with a remainder of 548.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 548, we get 548.
Grab the next digit (6) from the dividend, add it to 548, then carry on: 5486 / 809

Going ahead to step 5:
When dividing 5486 by 809, we get 6 with a remainder of 632.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtract 4854 from 5486 to get 632.
Include the next digit (0) from the dividend after 632, then repeat: 6320 / 809

On to step 6:
When dividing 6320 by 809, we get 7 with a remainder of 657.
Put 7 as the next digit of the answer. 
Result so far: 1067.0
If we take 5663 away from 6320, we end up with 657.
Bring next digit (6) of the dividend behind the 657 and repeat the process: 6576 / 809

Let's proceed to step 7:
When dividing 6576 by 809, we get 8 with a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 10678.0
Subtract 6472 from 6576 to get 104.
Bring next digit (5) of the dividend behind the 104 and repeat the process: 1045 / 809

On to step 8:
If we divide 1045 by 809, we get 1 and a remainder of 236.
The next digit of our result is 1. 
Result so far: 106781.0
If we subtract 809 from 1045, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 9:
When dividing 2360 by 809, we get 2 with a remainder of 742.
Record the quotient 2 as the next digit in the result. 
Result so far: 106781.2
Subtracting 1618 from 2360 leaves us with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 10:
7420 divided by 809 is 9 with a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 106781.29
The remainder is 139 after subtracting 7281 from 7420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Moving on to step 11:
If we divide 1390 by 809, we get 1 and a remainder of 581.
Use 1 as the next digit of our solution. 
Result so far: 106781.291
The remainder is 581 after subtracting 809 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

On to step 12:
809 goes into 5810 7 times with a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 106781.2917
If we subtract 5663 from 5810, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 13:
The number 809 fits into 1470 1 times, leaving a remainder of 661.
Record the quotient 1 as the next digit in the result. 
Result so far: 106781.29171
The remainder is 661 after subtracting 809 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Moving on to step 14:
809 can be fit into 6610 8 times, resulting in a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 106781.291718
The remainder is 138 after subtracting 6472 from 6610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 15:
1380 divided by 809 is 1 with a remainder of 571.
The next digit of our result is 1. 
Result so far: 106781.2917181
Deduct 809 from 1380 and we're left with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 16:
When dividing 5710 by 809, we get 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 106781.29171817
The remainder is 47 after subtracting 5663 from 5710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 106781.29171817, with a leftover of 4.7e-08.
