We're dividing 978971 by 99 
We want to figure out the number of times 978971 can be divided by 99.

On to step 1:
When dividing 9 by 99, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
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

Moving on to step 2:
When dividing 97 by 99, we get 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Bring next digit (8) of the dividend behind the 97 and repeat the process: 978 / 99

Step 3:
If we divide 978 by 99, we get 9 and a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 891 from 978 to get 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 99

Let's proceed to step 4:
879 divided by 99 is 8 with a remainder of 87.
Write down 8 as next digit of the result. 
Result so far: 98.0
The remainder is 87 after subtracting 792 from 879.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 99

Moving on to step 5:
99 goes into 877 8 times with a remainder of 85.
The next digit of our result is 8. 
Result so far: 988.0
Subtracting 792 from 877 leaves us with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 99

Let's proceed to step 6:
99 can be fit into 851 8 times, resulting in a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 9888.0
The remainder is 59 after subtracting 792 from 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
99 can be fit into 590 5 times, resulting in a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 9888.5
Subtract 495 from 590 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 8:
99 can be fit into 950 9 times, resulting in a remainder of 59.
The next digit of our result is 9. 
Result so far: 9888.59
Deduct 891 from 950 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
590 divided by 99 is 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 9888.595
Subtract 495 from 590 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 10:
When dividing 950 by 99, we get 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 9888.5959
Subtract 891 from 950 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 11:
99 can be fit into 590 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 9888.59595
Subtracting 495 from 590 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 12:
99 can be fit into 950 9 times, resulting in a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 9888.595959
The remainder is 59 after subtracting 891 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 13:
When dividing 590 by 99, we get 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 9888.5959595
If we take 495 away from 590, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 14:
99 can be fit into 950 9 times, resulting in a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 9888.59595959
Deduct 891 from 950 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final result is 9888.59595959 with a remainder of 5.9e-08.
