We look at the division of 10528851 by 809 
We're looking to find how many times 809 goes into 10528851.

Step 1:
809 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 809

Let's proceed to step 2:
If we divide 10 by 809, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 809

On to step 3:
809 goes into 105 0 times with a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 105, we end up with 105.
Append the next digit (2) from the dividend to 105 and continue with: 1052 / 809

Advancing to step 4:
1052 divided by 809 is 1 with a remainder of 243.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 809 from 1052 to get 243.
Grab the next digit (8) from the dividend, add it to 243, then carry on: 2438 / 809

On to step 5:
809 goes into 2438 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 2427 from 2438 and we're left with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 809

Moving on to step 6:
The number 809 fits into 118 0 times, leaving a remainder of 118.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we take 0 away from 118, we end up with 118.
Include the next digit (5) from the dividend after 118, then repeat: 1185 / 809

Going ahead to step 7:
809 can be fit into 1185 1 times, resulting in a remainder of 376.
Put 1 as the next digit of the answer. 
Result so far: 1301.0
Subtract 809 from 1185 to get 376.
Fetch the next digit (1) from the dividend, attach it to 376 and continue: 3761 / 809

Advancing to step 8:
3761 divided by 809 is 4 with a remainder of 525.
Put 4 as the next digit of the answer. 
Result so far: 13014.0
Subtracting 3236 from 3761 leaves us with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 9:
809 can be fit into 5250 6 times, resulting in a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 13014.6
The remainder is 396 after subtracting 4854 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 10:
The number 809 fits into 3960 4 times, leaving a remainder of 724.
Write down 4 as next digit of the result. 
Result so far: 13014.64
If we subtract 3236 from 3960, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Step 11:
When dividing 7240 by 809, we get 8 with a remainder of 768.
Put 8 as the next digit of the answer. 
Result so far: 13014.648
The remainder is 768 after subtracting 6472 from 7240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 12:
When dividing 7680 by 809, we get 9 with a remainder of 399.
Write down 9 as next digit of the result. 
Result so far: 13014.6489
The remainder is 399 after subtracting 7281 from 7680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 13:
3990 divided by 809 is 4 with a remainder of 754.
Use 4 as the next digit of our solution. 
Result so far: 13014.64894
Subtract 3236 from 3990 to get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Going ahead to step 14:
809 goes into 7540 9 times with a remainder of 259.
Write down 9 as next digit of the result. 
Result so far: 13014.648949
Subtract 7281 from 7540 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 15:
809 goes into 2590 3 times with a remainder of 163.
Use 3 as the next digit of our solution. 
Result so far: 13014.6489493
If we take 2427 away from 2590, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 16:
809 can be fit into 1630 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 13014.64894932
The remainder is 12 after subtracting 1618 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 13014.64894932, and the remainder is 1.2e-08.
