97002409 ÷ 991 
We want to figure out the number of times 97002409 can be divided by 991.

Advancing to step 1:
991 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 991

Moving on to step 2:
97 divided by 991 is 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Include the next digit (0) from the dividend after 97, then repeat: 970 / 991

Step 3:
When dividing 970 by 991, we get 0 with a remainder of 970.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 970 and we're left with 970.
Fetch the next digit (0) from the dividend, attach it to 970 and continue: 9700 / 991

Step 4:
9700 divided by 991 is 9 with a remainder of 781.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 8919 from 9700 to get 781.
Append the next digit (2) from the dividend to 781 and continue with: 7812 / 991

Moving on to step 5:
When dividing 7812 by 991, we get 7 with a remainder of 875.
Use 7 as the next digit of our solution. 
Result so far: 97.0
The remainder is 875 after subtracting 6937 from 7812.
Bring next digit (4) of the dividend behind the 875 and repeat the process: 8754 / 991

Let's proceed to step 6:
When dividing 8754 by 991, we get 8 with a remainder of 826.
The next digit of our result is 8. 
Result so far: 978.0
Subtracting 7928 from 8754 leaves us with 826.
Take the next digit (0) from the dividend and append it to 826, then repeat: 8260 / 991

Let's proceed to step 7:
When dividing 8260 by 991, we get 8 with a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 9788.0
Deduct 7928 from 8260 and we're left with 332.
Append the next digit (9) from the dividend to 332 and continue with: 3329 / 991

Step 8:
991 goes into 3329 3 times with a remainder of 356.
Use 3 as the next digit of our solution. 
Result so far: 97883.0
The remainder is 356 after subtracting 2973 from 3329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 9:
991 goes into 3560 3 times with a remainder of 587.
The next digit of our result is 3. 
Result so far: 97883.3
The remainder is 587 after subtracting 2973 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

On to step 10:
When dividing 5870 by 991, we get 5 with a remainder of 915.
The number 5 becomes the next digit in our result. 
Result so far: 97883.35
Subtract 4955 from 5870 to get 915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9150, and continue the process.

Step 11:
9150 divided by 991 is 9 with a remainder of 231.
Write down 9 as next digit of the result. 
Result so far: 97883.359
Subtract 8919 from 9150 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 12:
991 goes into 2310 2 times with a remainder of 328.
The number 2 becomes the next digit in our result. 
Result so far: 97883.3592
If we take 1982 away from 2310, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 13:
3280 divided by 991 is 3 with a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 97883.35923
Subtract 2973 from 3280 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 14:
If we divide 3070 by 991, we get 3 and a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 97883.359233
Subtracting 2973 from 3070 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

In conclusion, the division gives 97883.359233 with a balance of 9.7e-06.
