Let's divide 256136 by 91
We want to figure out the number of times 256136 can be divided by 91.

Step 1:
91 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 91

Advancing to step 2:
25 divided by 91 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 91

Step 3:
91 can be fit into 256 2 times, resulting in a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 182 from 256, we get 74.
Grab the next digit (1) from the dividend, add it to 74, then carry on: 741 / 91

Going ahead to step 4:
If we divide 741 by 91, we get 8 and a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 728 from 741, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 91

On to step 5:
When dividing 133 by 91, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 281.0
Deduct 91 from 133 and we're left with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 91

Moving on to step 6:
When dividing 426 by 91, we get 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 2814.0
Deduct 364 from 426 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
If we divide 620 by 91, we get 6 and a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 2814.6
The remainder is 74 after subtracting 546 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 8:
740 divided by 91 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2814.68
Deduct 728 from 740 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 91 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 2814.681
The remainder is 29 after subtracting 91 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
If we divide 290 by 91, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 2814.6813
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
If we divide 170 by 91, we get 1 and a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 2814.68131
Subtracting 91 from 170 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 12:
The number 91 fits into 790 8 times, leaving a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 2814.681318
If we take 728 away from 790, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
91 goes into 620 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 2814.6813186
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
When dividing 740 by 91, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 2814.68131868
The remainder is 12 after subtracting 728 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 2814.68131868, with a leftover of 1.2e-08.
