55277677 ÷ 991 
Our goal is to divide 55277677 by 991.

Step 1:
The number 991 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 991

Going ahead to step 2:
991 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 991

Advancing to step 3:
991 can be fit into 552 0 times, resulting in a remainder of 552.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 552 and we're left with 552.
Take the next digit (7) from the dividend and append it to 552, then repeat: 5527 / 991

Advancing to step 4:
5527 divided by 991 is 5 with a remainder of 572.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4955 from 5527 and we're left with 572.
Include the next digit (7) from the dividend after 572, then repeat: 5727 / 991

Let's proceed to step 5:
991 can be fit into 5727 5 times, resulting in a remainder of 772.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtract 4955 from 5727 to get 772.
Append the next digit (6) from the dividend to 772 and continue with: 7726 / 991

Step 6:
991 goes into 7726 7 times with a remainder of 789.
The number 7 becomes the next digit in our result. 
Result so far: 557.0
Subtracting 6937 from 7726 leaves us with 789.
Include the next digit (7) from the dividend after 789, then repeat: 7897 / 991

Advancing to step 7:
991 can be fit into 7897 7 times, resulting in a remainder of 960.
Record the quotient 7 as the next digit in the result. 
Result so far: 5577.0
If we take 6937 away from 7897, we end up with 960.
Bring next digit (7) of the dividend behind the 960 and repeat the process: 9607 / 991

Moving on to step 8:
The number 991 fits into 9607 9 times, leaving a remainder of 688.
The number 9 becomes the next digit in our result. 
Result so far: 55779.0
Subtract 8919 from 9607 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 9:
The number 991 fits into 6880 6 times, leaving a remainder of 934.
Record the quotient 6 as the next digit in the result. 
Result so far: 55779.6
If we subtract 5946 from 6880, we get 934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

On to step 10:
If we divide 9340 by 991, we get 9 and a remainder of 421.
The next digit of our result is 9. 
Result so far: 55779.69
If we take 8919 away from 9340, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 11:
If we divide 4210 by 991, we get 4 and a remainder of 246.
Use 4 as the next digit of our solution. 
Result so far: 55779.694
The remainder is 246 after subtracting 3964 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 12:
If we divide 2460 by 991, we get 2 and a remainder of 478.
Record the quotient 2 as the next digit in the result. 
Result so far: 55779.6942
Deduct 1982 from 2460 and we're left with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 13:
The number 991 fits into 4780 4 times, leaving a remainder of 816.
Write down 4 as next digit of the result. 
Result so far: 55779.69424
If we take 3964 away from 4780, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Step 14:
991 can be fit into 8160 8 times, resulting in a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 55779.694248
The remainder is 232 after subtracting 7928 from 8160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 15:
991 goes into 2320 2 times with a remainder of 338.
Use 2 as the next digit of our solution. 
Result so far: 55779.6942482
Subtract 1982 from 2320 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 16:
When dividing 3380 by 991, we get 3 with a remainder of 407.
The next digit of our result is 3. 
Result so far: 55779.69424823
Deduct 2973 from 3380 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

The final result is 55779.69424823 with a remainder of 4.07e-07.
