259919 divided by 91 
Our goal is to divide 259919 by 91.

Step 1:
When dividing 2 by 91, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 91

Moving on to step 2:
When dividing 25 by 91, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 91

On to step 3:
91 can be fit into 259 2 times, resulting in a remainder of 77.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 182 from 259 and we're left with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 91

Going ahead to step 4:
When dividing 779 by 91, we get 8 with a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 728 from 779 to get 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 91

On to step 5:
511 divided by 91 is 5 with a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 285.0
Deduct 455 from 511 and we're left with 56.
Grab the next digit (9) from the dividend, add it to 56, then carry on: 569 / 91

On to step 6:
569 divided by 91 is 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 2856.0
Deduct 546 from 569 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
230 divided by 91 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2856.2
Subtract 182 from 230 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
If we divide 480 by 91, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 2856.25
The remainder is 25 after subtracting 455 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 91 fits into 250 2 times, leaving a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 2856.252
Subtracting 182 from 250 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
The number 91 fits into 680 7 times, leaving a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 2856.2527
If we subtract 637 from 680, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 11:
91 can be fit into 430 4 times, resulting in a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 2856.25274
If we subtract 364 from 430, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
91 goes into 660 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 2856.252747
Subtracting 637 from 660 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
91 can be fit into 230 2 times, resulting in a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 2856.2527472
Deduct 182 from 230 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
480 divided by 91 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2856.25274725
Subtract 455 from 480 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 2856.25274725, with a leftover of 2.5e-08.
