We're dividing 54397504 by 991 
Our goal is to divide 54397504 by 991.

Going ahead to step 1:
991 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 991

Let's proceed to step 2:
When dividing 54 by 991, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 991

Step 3:
The number 991 fits into 543 0 times, leaving a remainder of 543.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 543 to get 543.
Include the next digit (9) from the dividend after 543, then repeat: 5439 / 991

Let's proceed to step 4:
991 goes into 5439 5 times with a remainder of 484.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 4955 from 5439 leaves us with 484.
Append the next digit (7) from the dividend to 484 and continue with: 4847 / 991

On to step 5:
4847 divided by 991 is 4 with a remainder of 883.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 3964 from 4847, we get 883.
Append the next digit (5) from the dividend to 883 and continue with: 8835 / 991

Moving on to step 6:
8835 divided by 991 is 8 with a remainder of 907.
The next digit of our result is 8. 
Result so far: 548.0
Subtract 7928 from 8835 to get 907.
Bring next digit (0) of the dividend behind the 907 and repeat the process: 9070 / 991

Let's proceed to step 7:
991 goes into 9070 9 times with a remainder of 151.
The next digit of our result is 9. 
Result so far: 5489.0
Subtract 8919 from 9070 to get 151.
Append the next digit (4) from the dividend to 151 and continue with: 1514 / 991

Let's proceed to step 8:
991 goes into 1514 1 times with a remainder of 523.
Put 1 as the next digit of the answer. 
Result so far: 54891.0
The remainder is 523 after subtracting 991 from 1514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 9:
The number 991 fits into 5230 5 times, leaving a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 54891.5
Subtract 4955 from 5230 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 10:
The number 991 fits into 2750 2 times, leaving a remainder of 768.
The number 2 becomes the next digit in our result. 
Result so far: 54891.52
If we take 1982 away from 2750, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Moving on to step 11:
991 can be fit into 7680 7 times, resulting in a remainder of 743.
Record the quotient 7 as the next digit in the result. 
Result so far: 54891.527
Subtract 6937 from 7680 to get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Advancing to step 12:
If we divide 7430 by 991, we get 7 and a remainder of 493.
The next digit of our result is 7. 
Result so far: 54891.5277
If we take 6937 away from 7430, we end up with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

The quotient of the division is 54891.5277, and the remainder is 0.00493.
