99054777 ÷ 291 
Our goal is to divide 99054777 by 291.

Going ahead to step 1:
When dividing 9 by 291, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 291

On to step 2:
If we divide 99 by 291, we get 0 and a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Append the next digit (0) from the dividend to 99 and continue with: 990 / 291

Advancing to step 3:
When dividing 990 by 291, we get 3 with a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 117 after subtracting 873 from 990.
Take the next digit (5) from the dividend and append it to 117, then repeat: 1175 / 291

On to step 4:
The number 291 fits into 1175 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 1164 from 1175 leaves us with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 291

Step 5:
291 can be fit into 114 0 times, resulting in a remainder of 114.
Use 0 as the next digit of our solution. 
Result so far: 340.0
If we subtract 0 from 114, we get 114.
Grab the next digit (7) from the dividend, add it to 114, then carry on: 1147 / 291

On to step 6:
291 can be fit into 1147 3 times, resulting in a remainder of 274.
Record the quotient 3 as the next digit in the result. 
Result so far: 3403.0
Deduct 873 from 1147 and we're left with 274.
Include the next digit (7) from the dividend after 274, then repeat: 2747 / 291

Advancing to step 7:
If we divide 2747 by 291, we get 9 and a remainder of 128.
Put 9 as the next digit of the answer. 
Result so far: 34039.0
If we take 2619 away from 2747, we end up with 128.
Bring next digit (7) of the dividend behind the 128 and repeat the process: 1287 / 291

Advancing to step 8:
291 goes into 1287 4 times with a remainder of 123.
Write down 4 as next digit of the result. 
Result so far: 340394.0
If we subtract 1164 from 1287, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 9:
1230 divided by 291 is 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 340394.4
The remainder is 66 after subtracting 1164 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
When dividing 660 by 291, we get 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 340394.42
Subtracting 582 from 660 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
The number 291 fits into 780 2 times, leaving a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 340394.422
Deduct 582 from 780 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Our division results in 340394.422 with a remaining 0.0198.
