33878960 divided by 991 
We're looking to find how many times 991 goes into 33878960.

Moving on to step 1:
991 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 991

Advancing to step 2:
991 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 991

Going ahead to step 3:
991 goes into 338 0 times with a remainder of 338.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 338, we get 338.
Fetch the next digit (7) from the dividend, attach it to 338 and continue: 3387 / 991

Moving on to step 4:
3387 divided by 991 is 3 with a remainder of 414.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2973 from 3387, we get 414.
Fetch the next digit (8) from the dividend, attach it to 414 and continue: 4148 / 991

On to step 5:
991 can be fit into 4148 4 times, resulting in a remainder of 184.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 3964 from 4148 leaves us with 184.
Bring next digit (9) of the dividend behind the 184 and repeat the process: 1849 / 991

Moving on to step 6:
1849 divided by 991 is 1 with a remainder of 858.
Use 1 as the next digit of our solution. 
Result so far: 341.0
If we subtract 991 from 1849, we get 858.
Include the next digit (6) from the dividend after 858, then repeat: 8586 / 991

Moving on to step 7:
The number 991 fits into 8586 8 times, leaving a remainder of 658.
The number 8 becomes the next digit in our result. 
Result so far: 3418.0
Subtract 7928 from 8586 to get 658.
Include the next digit (0) from the dividend after 658, then repeat: 6580 / 991

Step 8:
991 goes into 6580 6 times with a remainder of 634.
Use 6 as the next digit of our solution. 
Result so far: 34186.0
Deduct 5946 from 6580 and we're left with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Step 9:
991 can be fit into 6340 6 times, resulting in a remainder of 394.
Record the quotient 6 as the next digit in the result. 
Result so far: 34186.6
Subtract 5946 from 6340 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 10:
When dividing 3940 by 991, we get 3 with a remainder of 967.
Use 3 as the next digit of our solution. 
Result so far: 34186.63
Subtract 2973 from 3940 to get 967.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9670, and continue the process.

Advancing to step 11:
The number 991 fits into 9670 9 times, leaving a remainder of 751.
Write down 9 as next digit of the result. 
Result so far: 34186.639
If we take 8919 away from 9670, we end up with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Going ahead to step 12:
If we divide 7510 by 991, we get 7 and a remainder of 573.
The next digit of our result is 7. 
Result so far: 34186.6397
Subtracting 6937 from 7510 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

On to step 13:
5730 divided by 991 is 5 with a remainder of 775.
Use 5 as the next digit of our solution. 
Result so far: 34186.63975
Deduct 4955 from 5730 and we're left with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Let's proceed to step 14:
The number 991 fits into 7750 7 times, leaving a remainder of 813.
The next digit of our result is 7. 
Result so far: 34186.639757
Subtract 6937 from 7750 to get 813.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

Moving on to step 15:
991 goes into 8130 8 times with a remainder of 202.
The number 8 becomes the next digit in our result. 
Result so far: 34186.6397578
If we take 7928 away from 8130, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 16:
When dividing 2020 by 991, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 34186.63975782
The remainder is 38 after subtracting 1982 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 34186.63975782 with a balance of 3.8e-08.
