Let's divide 85539042 by 810
Let's see how many times 810 fits into 85539042.

Moving on to step 1:
The number 810 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 810

Going ahead to step 2:
The number 810 fits into 85 0 times, leaving a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Include the next digit (5) from the dividend after 85, then repeat: 855 / 810

Advancing to step 3:
When dividing 855 by 810, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 810 away from 855, we end up with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 810

Advancing to step 4:
When dividing 453 by 810, we get 0 with a remainder of 453.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 453 and we're left with 453.
Fetch the next digit (9) from the dividend, attach it to 453 and continue: 4539 / 810

Moving on to step 5:
4539 divided by 810 is 5 with a remainder of 489.
Write down 5 as next digit of the result. 
Result so far: 105.0
The remainder is 489 after subtracting 4050 from 4539.
Grab the next digit (0) from the dividend, add it to 489, then carry on: 4890 / 810

Going ahead to step 6:
4890 divided by 810 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 1056.0
If we take 4860 away from 4890, we end up with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 810

Going ahead to step 7:
If we divide 304 by 810, we get 0 and a remainder of 304.
Use 0 as the next digit of our solution. 
Result so far: 10560.0
If we subtract 0 from 304, we get 304.
Take the next digit (2) from the dividend and append it to 304, then repeat: 3042 / 810

Let's proceed to step 8:
When dividing 3042 by 810, we get 3 with a remainder of 612.
Write down 3 as next digit of the result. 
Result so far: 105603.0
Subtract 2430 from 3042 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 9:
810 can be fit into 6120 7 times, resulting in a remainder of 450.
Write down 7 as next digit of the result. 
Result so far: 105603.7
Deduct 5670 from 6120 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
The number 810 fits into 4500 5 times, leaving a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 105603.75
If we subtract 4050 from 4500, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 11:
When dividing 4500 by 810, we get 5 with a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 105603.755
Deduct 4050 from 4500 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

After the division, we end up with 105603.755 and a remainder of 0.045.
