978880 ÷ 99 
Let's see how many times 99 fits into 978880.

On to step 1:
When dividing 9 by 99, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 99

Let's proceed to step 2:
The number 99 fits into 97 0 times, leaving a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Fetch the next digit (8) from the dividend, attach it to 97 and continue: 978 / 99

Step 3:
978 divided by 99 is 9 with a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 891 from 978 and we're left with 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 99

Step 4:
The number 99 fits into 878 8 times, leaving a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtract 792 from 878 to get 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 99

Step 5:
When dividing 868 by 99, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
Subtracting 792 from 868 leaves us with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 99

Advancing to step 6:
760 divided by 99 is 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 9887.0
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
The number 99 fits into 670 6 times, leaving a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 9887.6
If we take 594 away from 670, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 8:
99 goes into 760 7 times with a remainder of 67.
The next digit of our result is 7. 
Result so far: 9887.67
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
If we divide 670 by 99, we get 6 and a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 9887.676
Subtract 594 from 670 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
99 goes into 760 7 times with a remainder of 67.
The next digit of our result is 7. 
Result so far: 9887.6767
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 11:
670 divided by 99 is 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 9887.67676
The remainder is 76 after subtracting 594 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
If we divide 760 by 99, we get 7 and a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 9887.676767
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 13:
99 goes into 670 6 times with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 9887.6767676
The remainder is 76 after subtracting 594 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
760 divided by 99 is 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 9887.67676767
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Our division results in 9887.67676767 with a remaining 6.7e-08.
