We're dividing 83073993 by 991 
We want to figure out the number of times 83073993 can be divided by 991.

Let's proceed to step 1:
991 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 991

Advancing to step 2:
When dividing 83 by 991, we get 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Append the next digit (0) from the dividend to 83 and continue with: 830 / 991

Moving on to step 3:
991 goes into 830 0 times with a remainder of 830.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 830 to get 830.
Bring next digit (7) of the dividend behind the 830 and repeat the process: 8307 / 991

On to step 4:
The number 991 fits into 8307 8 times, leaving a remainder of 379.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7928 away from 8307, we end up with 379.
Bring next digit (3) of the dividend behind the 379 and repeat the process: 3793 / 991

On to step 5:
If we divide 3793 by 991, we get 3 and a remainder of 820.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 2973 from 3793 and we're left with 820.
Grab the next digit (9) from the dividend, add it to 820, then carry on: 8209 / 991

Moving on to step 6:
When dividing 8209 by 991, we get 8 with a remainder of 281.
Use 8 as the next digit of our solution. 
Result so far: 838.0
Subtract 7928 from 8209 to get 281.
Fetch the next digit (9) from the dividend, attach it to 281 and continue: 2819 / 991

Moving on to step 7:
991 can be fit into 2819 2 times, resulting in a remainder of 837.
Use 2 as the next digit of our solution. 
Result so far: 8382.0
If we take 1982 away from 2819, we end up with 837.
Grab the next digit (3) from the dividend, add it to 837, then carry on: 8373 / 991

Moving on to step 8:
When dividing 8373 by 991, we get 8 with a remainder of 445.
Use 8 as the next digit of our solution. 
Result so far: 83828.0
The remainder is 445 after subtracting 7928 from 8373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 9:
4450 divided by 991 is 4 with a remainder of 486.
Use 4 as the next digit of our solution. 
Result so far: 83828.4
If we subtract 3964 from 4450, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 10:
991 goes into 4860 4 times with a remainder of 896.
Write down 4 as next digit of the result. 
Result so far: 83828.44
The remainder is 896 after subtracting 3964 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8960, and continue the process.

In conclusion, the division gives 83828.44 with a balance of 0.896.
