We're dividing 869859 by 99 
Our goal is to divide 869859 by 99.

Step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 99

Going ahead to step 2:
99 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 99

Advancing to step 3:
When dividing 869 by 99, we get 8 with a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 792 from 869 to get 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 99

Going ahead to step 4:
When dividing 778 by 99, we get 7 with a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 87.0
The remainder is 85 after subtracting 693 from 778.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 99

Step 5:
If we divide 855 by 99, we get 8 and a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 878.0
The remainder is 63 after subtracting 792 from 855.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 99

Going ahead to step 6:
99 can be fit into 639 6 times, resulting in a remainder of 45.
The next digit of our result is 6. 
Result so far: 8786.0
If we subtract 594 from 639, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
When dividing 450 by 99, we get 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 8786.4
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 8786.45
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
99 goes into 450 4 times with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 8786.454
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
If we divide 540 by 99, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 8786.4545
Deduct 495 from 540 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
When dividing 450 by 99, we get 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 8786.45454
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
99 goes into 540 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 8786.454545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
When dividing 450 by 99, we get 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 8786.4545454
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
99 goes into 540 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 8786.45454545
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 8786.45454545 with a remainder of 4.5e-08.
