We're dividing 86872270 by 810 
We want to figure out the number of times 86872270 can be divided by 810.

Let's proceed to step 1:
810 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 810

Moving on to step 2:
810 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 810

Step 3:
The number 810 fits into 868 1 times, leaving a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 810 from 868 and we're left with 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 810

On to step 4:
587 divided by 810 is 0 with a remainder of 587.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 587 to get 587.
Grab the next digit (2) from the dividend, add it to 587, then carry on: 5872 / 810

Moving on to step 5:
The number 810 fits into 5872 7 times, leaving a remainder of 202.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 5670 from 5872 to get 202.
Append the next digit (2) from the dividend to 202 and continue with: 2022 / 810

Moving on to step 6:
If we divide 2022 by 810, we get 2 and a remainder of 402.
The next digit of our result is 2. 
Result so far: 1072.0
If we subtract 1620 from 2022, we get 402.
Take the next digit (7) from the dividend and append it to 402, then repeat: 4027 / 810

Step 7:
When dividing 4027 by 810, we get 4 with a remainder of 787.
Put 4 as the next digit of the answer. 
Result so far: 10724.0
If we take 3240 away from 4027, we end up with 787.
Bring next digit (0) of the dividend behind the 787 and repeat the process: 7870 / 810

Advancing to step 8:
If we divide 7870 by 810, we get 9 and a remainder of 580.
The next digit of our result is 9. 
Result so far: 107249.0
If we subtract 7290 from 7870, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 9:
5800 divided by 810 is 7 with a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 107249.7
Deduct 5670 from 5800 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
The number 810 fits into 1300 1 times, leaving a remainder of 490.
Record the quotient 1 as the next digit in the result. 
Result so far: 107249.71
If we subtract 810 from 1300, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 11:
4900 divided by 810 is 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 107249.716
Subtracting 4860 from 4900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
400 divided by 810 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 107249.716
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
4000 divided by 810 is 4 with a remainder of 760.
The number 4 becomes the next digit in our result. 
Result so far: 107249.71604
If we subtract 3240 from 4000, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 14:
When dividing 7600 by 810, we get 9 with a remainder of 310.
Record the quotient 9 as the next digit in the result. 
Result so far: 107249.716049
If we subtract 7290 from 7600, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 15:
When dividing 3100 by 810, we get 3 with a remainder of 670.
Write down 3 as next digit of the result. 
Result so far: 107249.7160493
The remainder is 670 after subtracting 2430 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 16:
810 goes into 6700 8 times with a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 107249.71604938
Subtract 6480 from 6700 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 107249.71604938 with a balance of 2.2e-07.
