We're dividing 260991 by 91 
We're looking to find how many times 91 goes into 260991.

Let's proceed to step 1:
91 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 91

Moving on to step 2:
91 goes into 26 0 times with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 91

Let's proceed to step 3:
260 divided by 91 is 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 182 from 260 and we're left with 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 91

Going ahead to step 4:
If we divide 789 by 91, we get 8 and a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 728 from 789 to get 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 91

Advancing to step 5:
When dividing 619 by 91, we get 6 with a remainder of 73.
Put 6 as the next digit of the answer. 
Result so far: 286.0
Subtract 546 from 619 to get 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 91

On to step 6:
The number 91 fits into 731 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 2868.0
Subtract 728 from 731 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 91, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2868.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
91 can be fit into 300 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 2868.03
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
91 can be fit into 270 2 times, resulting in a remainder of 88.
The next digit of our result is 2. 
Result so far: 2868.032
The remainder is 88 after subtracting 182 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 10:
880 divided by 91 is 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 2868.0329
Deduct 819 from 880 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
The number 91 fits into 610 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 2868.03296
Deduct 546 from 610 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
91 goes into 640 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 2868.032967
Deduct 637 from 640 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
When dividing 30 by 91, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2868.032967
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
If we divide 300 by 91, we get 3 and a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 2868.03296703
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 2868.03296703 and a remainder of 2.7e-08.
