We're dividing 869078 by 799 
We want to figure out the number of times 869078 can be divided by 799.

Going ahead to step 1:
If we divide 8 by 799, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 799

Step 2:
The number 799 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 799

Let's proceed to step 3:
799 goes into 869 1 times with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 799 from 869 and we're left with 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 799

Moving on to step 4:
700 divided by 799 is 0 with a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 700, we end up with 700.
Take the next digit (7) from the dividend and append it to 700, then repeat: 7007 / 799

Advancing to step 5:
7007 divided by 799 is 8 with a remainder of 615.
The next digit of our result is 8. 
Result so far: 108.0
If we take 6392 away from 7007, we end up with 615.
Include the next digit (8) from the dividend after 615, then repeat: 6158 / 799

Step 6:
When dividing 6158 by 799, we get 7 with a remainder of 565.
The next digit of our result is 7. 
Result so far: 1087.0
Deduct 5593 from 6158 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 7:
799 goes into 5650 7 times with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 1087.7
The remainder is 57 after subtracting 5593 from 5650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 8:
570 divided by 799 is 0 with a remainder of 570.
The next digit of our result is 0. 
Result so far: 1087.7
Subtracting 0 from 570 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 9:
When dividing 5700 by 799, we get 7 with a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 1087.707
If we subtract 5593 from 5700, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 10:
799 goes into 1070 1 times with a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 1087.7071
Subtracting 799 from 1070 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 11:
The number 799 fits into 2710 3 times, leaving a remainder of 313.
The next digit of our result is 3. 
Result so far: 1087.70713
Deduct 2397 from 2710 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 12:
If we divide 3130 by 799, we get 3 and a remainder of 733.
Record the quotient 3 as the next digit in the result. 
Result so far: 1087.707133
Deduct 2397 from 3130 and we're left with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

The final outcome is 1087.707133, with a leftover of 7.33e-05.
