75588371 ÷ 991 
Let's see how many times 991 fits into 75588371.

Moving on to step 1:
991 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 991

Step 2:
When dividing 75 by 991, we get 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 991

On to step 3:
When dividing 755 by 991, we get 0 with a remainder of 755.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 755, we end up with 755.
Include the next digit (8) from the dividend after 755, then repeat: 7558 / 991

Moving on to step 4:
When dividing 7558 by 991, we get 7 with a remainder of 621.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 6937 from 7558, we get 621.
Include the next digit (8) from the dividend after 621, then repeat: 6218 / 991

Moving on to step 5:
The number 991 fits into 6218 6 times, leaving a remainder of 272.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 5946 away from 6218, we end up with 272.
Bring next digit (3) of the dividend behind the 272 and repeat the process: 2723 / 991

Moving on to step 6:
When dividing 2723 by 991, we get 2 with a remainder of 741.
Put 2 as the next digit of the answer. 
Result so far: 762.0
Deduct 1982 from 2723 and we're left with 741.
Include the next digit (7) from the dividend after 741, then repeat: 7417 / 991

Step 7:
7417 divided by 991 is 7 with a remainder of 480.
Put 7 as the next digit of the answer. 
Result so far: 7627.0
Subtracting 6937 from 7417 leaves us with 480.
Take the next digit (1) from the dividend and append it to 480, then repeat: 4801 / 991

Step 8:
When dividing 4801 by 991, we get 4 with a remainder of 837.
The number 4 becomes the next digit in our result. 
Result so far: 76274.0
The remainder is 837 after subtracting 3964 from 4801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Let's proceed to step 9:
When dividing 8370 by 991, we get 8 with a remainder of 442.
Use 8 as the next digit of our solution. 
Result so far: 76274.8
Deduct 7928 from 8370 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 10:
991 goes into 4420 4 times with a remainder of 456.
Write down 4 as next digit of the result. 
Result so far: 76274.84
Subtracting 3964 from 4420 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 11:
991 goes into 4560 4 times with a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 76274.844
If we subtract 3964 from 4560, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

The final outcome is 76274.844, with a leftover of 0.0596.
