27037873 ÷ 810 
We want to figure out the number of times 27037873 can be divided by 810.

On to step 1:
810 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 810

Advancing to step 2:
The number 810 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 810

Going ahead to step 3:
When dividing 270 by 810, we get 0 with a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 270 to get 270.
Include the next digit (3) from the dividend after 270, then repeat: 2703 / 810

Moving on to step 4:
810 can be fit into 2703 3 times, resulting in a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 273 after subtracting 2430 from 2703.
Take the next digit (7) from the dividend and append it to 273, then repeat: 2737 / 810

On to step 5:
The number 810 fits into 2737 3 times, leaving a remainder of 307.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 2430 away from 2737, we end up with 307.
Append the next digit (8) from the dividend to 307 and continue with: 3078 / 810

On to step 6:
810 goes into 3078 3 times with a remainder of 648.
Put 3 as the next digit of the answer. 
Result so far: 333.0
If we subtract 2430 from 3078, we get 648.
Append the next digit (7) from the dividend to 648 and continue with: 6487 / 810

Moving on to step 7:
When dividing 6487 by 810, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 3338.0
Subtracting 6480 from 6487 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 810

On to step 8:
810 can be fit into 73 0 times, resulting in a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 33380.0
The remainder is 73 after subtracting 0 from 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
810 goes into 730 0 times with a remainder of 730.
Use 0 as the next digit of our solution. 
Result so far: 33380.0
If we take 0 away from 730, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 10:
The number 810 fits into 7300 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 33380.09
Subtract 7290 from 7300 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
When dividing 100 by 810, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 33380.09
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
1000 divided by 810 is 1 with a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 33380.0901
The remainder is 190 after subtracting 810 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 13:
The number 810 fits into 1900 2 times, leaving a remainder of 280.
The next digit of our result is 2. 
Result so far: 33380.09012
Deduct 1620 from 1900 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 14:
810 goes into 2800 3 times with a remainder of 370.
The number 3 becomes the next digit in our result. 
Result so far: 33380.090123
If we subtract 2430 from 2800, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 15:
When dividing 3700 by 810, we get 4 with a remainder of 460.
Use 4 as the next digit of our solution. 
Result so far: 33380.0901234
If we take 3240 away from 3700, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
810 can be fit into 4600 5 times, resulting in a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 33380.09012345
Subtract 4050 from 4600 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Our division results in 33380.09012345 with a remaining 5.5e-07.
