We look at the division of 85690969 by 810 
We're looking to find how many times 810 goes into 85690969.

On to step 1:
8 divided by 810 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 810

Let's proceed to step 2:
810 goes into 85 0 times with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Bring next digit (6) of the dividend behind the 85 and repeat the process: 856 / 810

Step 3:
810 can be fit into 856 1 times, resulting in a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 810 from 856 leaves us with 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 810

Advancing to step 4:
810 can be fit into 469 0 times, resulting in a remainder of 469.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 469, we end up with 469.
Grab the next digit (0) from the dividend, add it to 469, then carry on: 4690 / 810

Step 5:
810 can be fit into 4690 5 times, resulting in a remainder of 640.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtracting 4050 from 4690 leaves us with 640.
Bring next digit (9) of the dividend behind the 640 and repeat the process: 6409 / 810

Going ahead to step 6:
810 can be fit into 6409 7 times, resulting in a remainder of 739.
Put 7 as the next digit of the answer. 
Result so far: 1057.0
Subtracting 5670 from 6409 leaves us with 739.
Bring next digit (6) of the dividend behind the 739 and repeat the process: 7396 / 810

On to step 7:
If we divide 7396 by 810, we get 9 and a remainder of 106.
The next digit of our result is 9. 
Result so far: 10579.0
Subtracting 7290 from 7396 leaves us with 106.
Fetch the next digit (9) from the dividend, attach it to 106 and continue: 1069 / 810

Let's proceed to step 8:
810 goes into 1069 1 times with a remainder of 259.
The next digit of our result is 1. 
Result so far: 105791.0
The remainder is 259 after subtracting 810 from 1069.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 9:
2590 divided by 810 is 3 with a remainder of 160.
The next digit of our result is 3. 
Result so far: 105791.3
Subtracting 2430 from 2590 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
810 can be fit into 1600 1 times, resulting in a remainder of 790.
The number 1 becomes the next digit in our result. 
Result so far: 105791.31
If we subtract 810 from 1600, we get 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 11:
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: 105791.319
Subtracting 7290 from 7900 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 12:
810 can be fit into 6100 7 times, resulting in a remainder of 430.
The number 7 becomes the next digit in our result. 
Result so far: 105791.3197
The remainder is 430 after subtracting 5670 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 13:
The number 810 fits into 4300 5 times, leaving a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 105791.31975
The remainder is 250 after subtracting 4050 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
The number 810 fits into 2500 3 times, leaving a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 105791.319753
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 15:
700 divided by 810 is 0 with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 105791.319753
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 16:
810 can be fit into 7000 8 times, resulting in a remainder of 520.
Put 8 as the next digit of the answer. 
Result so far: 105791.31975308
Subtract 6480 from 7000 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final result is 105791.31975308 with a remainder of 5.2e-07.
