Let's divide 85278372 by 809
Let's see how many times 809 fits into 85278372.

Going ahead to step 1:
The number 809 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 809

Advancing to step 2:
809 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 809

Let's proceed to step 3:
809 can be fit into 852 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 809 from 852 and we're left with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 809

Going ahead to step 4:
809 goes into 437 0 times with a remainder of 437.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 437 and we're left with 437.
Include the next digit (8) from the dividend after 437, then repeat: 4378 / 809

Advancing to step 5:
If we divide 4378 by 809, we get 5 and a remainder of 333.
Use 5 as the next digit of our solution. 
Result so far: 105.0
The remainder is 333 after subtracting 4045 from 4378.
Fetch the next digit (3) from the dividend, attach it to 333 and continue: 3333 / 809

Moving on to step 6:
3333 divided by 809 is 4 with a remainder of 97.
The number 4 becomes the next digit in our result. 
Result so far: 1054.0
If we subtract 3236 from 3333, we get 97.
Append the next digit (7) from the dividend to 97 and continue with: 977 / 809

Advancing to step 7:
The number 809 fits into 977 1 times, leaving a remainder of 168.
Record the quotient 1 as the next digit in the result. 
Result so far: 10541.0
If we subtract 809 from 977, we get 168.
Bring next digit (2) of the dividend behind the 168 and repeat the process: 1682 / 809

Let's proceed to step 8:
809 can be fit into 1682 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 105412.0
Deduct 1618 from 1682 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
809 can be fit into 640 0 times, resulting in a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 105412.0
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 10:
6400 divided by 809 is 7 with a remainder of 737.
Record the quotient 7 as the next digit in the result. 
Result so far: 105412.07
If we subtract 5663 from 6400, we get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Going ahead to step 11:
809 can be fit into 7370 9 times, resulting in a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 105412.079
If we take 7281 away from 7370, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 12:
When dividing 890 by 809, we get 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 105412.0791
If we take 809 away from 890, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
The number 809 fits into 810 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 105412.07911
Subtract 809 from 810 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 105412.07911 with a remainder of 1e-06.
