8559286 ÷ 799 
We want to figure out the number of times 8559286 can be divided by 799.

Going ahead to step 1:
The number 799 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 799

Advancing to step 2:
When dividing 85 by 799, we get 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 799

Step 3:
When dividing 855 by 799, we get 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 799 from 855 to get 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 799

Advancing to step 4:
When dividing 569 by 799, we get 0 with a remainder of 569.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 569, we get 569.
Include the next digit (2) from the dividend after 569, then repeat: 5692 / 799

Step 5:
799 can be fit into 5692 7 times, resulting in a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we subtract 5593 from 5692, we get 99.
Fetch the next digit (8) from the dividend, attach it to 99 and continue: 998 / 799

On to step 6:
799 can be fit into 998 1 times, resulting in a remainder of 199.
The next digit of our result is 1. 
Result so far: 1071.0
The remainder is 199 after subtracting 799 from 998.
Fetch the next digit (6) from the dividend, attach it to 199 and continue: 1996 / 799

On to step 7:
799 can be fit into 1996 2 times, resulting in a remainder of 398.
Use 2 as the next digit of our solution. 
Result so far: 10712.0
Subtracting 1598 from 1996 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 8:
When dividing 3980 by 799, we get 4 with a remainder of 784.
Write down 4 as next digit of the result. 
Result so far: 10712.4
If we take 3196 away from 3980, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 9:
If we divide 7840 by 799, we get 9 and a remainder of 649.
Put 9 as the next digit of the answer. 
Result so far: 10712.49
If we take 7191 away from 7840, we end up with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Going ahead to step 10:
When dividing 6490 by 799, we get 8 with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 10712.498
Subtract 6392 from 6490 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 11:
799 can be fit into 980 1 times, resulting in a remainder of 181.
Put 1 as the next digit of the answer. 
Result so far: 10712.4981
Subtract 799 from 980 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 12:
If we divide 1810 by 799, we get 2 and a remainder of 212.
The next digit of our result is 2. 
Result so far: 10712.49812
If we subtract 1598 from 1810, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 13:
When dividing 2120 by 799, we get 2 with a remainder of 522.
Put 2 as the next digit of the answer. 
Result so far: 10712.498122
Subtract 1598 from 2120 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

The final outcome is 10712.498122, with a leftover of 5.22e-05.
