279987 ÷ 91 
We want to divide 279987 by 91.

On to step 1:
2 divided by 91 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 91

Advancing to step 2:
If we divide 27 by 91, we get 0 and a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 91

On to step 3:
279 divided by 91 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 6 after subtracting 273 from 279.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 91

On to step 4:
91 goes into 69 0 times with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 69, we get 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 91

On to step 5:
698 divided by 91 is 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
Subtract 637 from 698 to get 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 91

On to step 6:
If we divide 617 by 91, we get 6 and a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 3076.0
Subtracting 546 from 617 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
The number 91 fits into 710 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 3076.7
Subtracting 637 from 710 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 8:
91 goes into 730 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 3076.78
The remainder is 2 after subtracting 728 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
91 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3076.78
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 91, we get 2 and a remainder of 18.
The next digit of our result is 2. 
Result so far: 3076.7802
If we take 182 away from 200, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
The number 91 fits into 180 1 times, leaving a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 3076.78021
If we subtract 91 from 180, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 12:
When dividing 890 by 91, we get 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 3076.780219
If we subtract 819 from 890, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 13:
91 goes into 710 7 times with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 3076.7802197
The remainder is 73 after subtracting 637 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 14:
The number 91 fits into 730 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 3076.78021978
Subtract 728 from 730 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 3076.78021978 with a remainder of 2e-09.
