Let's divide 91543503 by 991
Our goal is to divide 91543503 by 991.

On to step 1:
991 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 991

Going ahead to step 2:
If we divide 91 by 991, we get 0 and a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Fetch the next digit (5) from the dividend, attach it to 91 and continue: 915 / 991

Moving on to step 3:
991 can be fit into 915 0 times, resulting in a remainder of 915.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 915, we get 915.
Include the next digit (4) from the dividend after 915, then repeat: 9154 / 991

On to step 4:
9154 divided by 991 is 9 with a remainder of 235.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 8919 from 9154 and we're left with 235.
Fetch the next digit (3) from the dividend, attach it to 235 and continue: 2353 / 991

Step 5:
The number 991 fits into 2353 2 times, leaving a remainder of 371.
Put 2 as the next digit of the answer. 
Result so far: 92.0
If we take 1982 away from 2353, we end up with 371.
Grab the next digit (5) from the dividend, add it to 371, then carry on: 3715 / 991

Let's proceed to step 6:
991 goes into 3715 3 times with a remainder of 742.
Write down 3 as next digit of the result. 
Result so far: 923.0
If we take 2973 away from 3715, we end up with 742.
Include the next digit (0) from the dividend after 742, then repeat: 7420 / 991

On to step 7:
7420 divided by 991 is 7 with a remainder of 483.
Write down 7 as next digit of the result. 
Result so far: 9237.0
Deduct 6937 from 7420 and we're left with 483.
Fetch the next digit (3) from the dividend, attach it to 483 and continue: 4833 / 991

Step 8:
991 can be fit into 4833 4 times, resulting in a remainder of 869.
Write down 4 as next digit of the result. 
Result so far: 92374.0
Subtracting 3964 from 4833 leaves us with 869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

Going ahead to step 9:
991 goes into 8690 8 times with a remainder of 762.
The next digit of our result is 8. 
Result so far: 92374.8
Subtract 7928 from 8690 to get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Moving on to step 10:
If we divide 7620 by 991, we get 7 and a remainder of 683.
Put 7 as the next digit of the answer. 
Result so far: 92374.87
Subtract 6937 from 7620 to get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Moving on to step 11:
991 goes into 6830 6 times with a remainder of 884.
Record the quotient 6 as the next digit in the result. 
Result so far: 92374.876
Deduct 5946 from 6830 and we're left with 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

On to step 12:
991 goes into 8840 8 times with a remainder of 912.
Put 8 as the next digit of the answer. 
Result so far: 92374.8768
Subtracting 7928 from 8840 leaves us with 912.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9120, and continue the process.

Going ahead to step 13:
The number 991 fits into 9120 9 times, leaving a remainder of 201.
Write down 9 as next digit of the result. 
Result so far: 92374.87689
The remainder is 201 after subtracting 8919 from 9120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 14:
991 can be fit into 2010 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 92374.876892
Deduct 1982 from 2010 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 15:
If we divide 280 by 991, we get 0 and a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 92374.876892
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 16:
2800 divided by 991 is 2 with a remainder of 818.
Use 2 as the next digit of our solution. 
Result so far: 92374.87689202
If we subtract 1982 from 2800, we get 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

After the division, we end up with 92374.87689202 and a remainder of 8.18e-07.
