We look at the division of 27851020 by 810 
We want to divide 27851020 by 810.

Let's proceed to step 1:
810 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 810

Step 2:
When dividing 27 by 810, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 810

Advancing to step 3:
810 goes into 278 0 times with a remainder of 278.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 278 after subtracting 0 from 278.
Bring next digit (5) of the dividend behind the 278 and repeat the process: 2785 / 810

Let's proceed to step 4:
810 can be fit into 2785 3 times, resulting in a remainder of 355.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2430 from 2785 to get 355.
Include the next digit (1) from the dividend after 355, then repeat: 3551 / 810

On to step 5:
When dividing 3551 by 810, we get 4 with a remainder of 311.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 3240 from 3551 leaves us with 311.
Bring next digit (0) of the dividend behind the 311 and repeat the process: 3110 / 810

Advancing to step 6:
810 can be fit into 3110 3 times, resulting in a remainder of 680.
The next digit of our result is 3. 
Result so far: 343.0
If we take 2430 away from 3110, we end up with 680.
Include the next digit (2) from the dividend after 680, then repeat: 6802 / 810

Step 7:
6802 divided by 810 is 8 with a remainder of 322.
Put 8 as the next digit of the answer. 
Result so far: 3438.0
If we subtract 6480 from 6802, we get 322.
Grab the next digit (0) from the dividend, add it to 322, then carry on: 3220 / 810

Advancing to step 8:
810 can be fit into 3220 3 times, resulting in a remainder of 790.
Write down 3 as next digit of the result. 
Result so far: 34383.0
Subtracting 2430 from 3220 leaves us with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 9:
The number 810 fits into 7900 9 times, leaving a remainder of 610.
Put 9 as the next digit of the answer. 
Result so far: 34383.9
Subtract 7290 from 7900 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 10:
The number 810 fits into 6100 7 times, leaving a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 34383.97
Deduct 5670 from 6100 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 11:
If we divide 4300 by 810, we get 5 and a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 34383.975
If we subtract 4050 from 4300, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
The number 810 fits into 2500 3 times, leaving a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 34383.9753
If we subtract 2430 from 2500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
810 goes into 700 0 times with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 34383.9753
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 14:
810 goes into 7000 8 times with a remainder of 520.
The number 8 becomes the next digit in our result. 
Result so far: 34383.975308
The remainder is 520 after subtracting 6480 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 15:
If we divide 5200 by 810, we get 6 and a remainder of 340.
The number 6 becomes the next digit in our result. 
Result so far: 34383.9753086
The remainder is 340 after subtracting 4860 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 16:
3400 divided by 810 is 4 with a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 34383.97530864
The remainder is 160 after subtracting 3240 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 34383.97530864, with a leftover of 1.6e-07.
