408086 ÷ 91 
Let's see how many times 91 fits into 408086.

Let's proceed to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 91

Moving on to step 2:
When dividing 40 by 91, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 91

Going ahead to step 3:
The number 91 fits into 408 4 times, leaving a remainder of 44.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 364 from 408 leaves us with 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 91

Step 4:
When dividing 440 by 91, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 364 from 440, we get 76.
Take the next digit (8) from the dividend and append it to 76, then repeat: 768 / 91

Going ahead to step 5:
91 goes into 768 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 448.0
Subtracting 728 from 768 leaves us with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 91

Let's proceed to step 6:
91 can be fit into 406 4 times, resulting in a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4484.0
Subtract 364 from 406 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
If we divide 420 by 91, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 4484.4
The remainder is 56 after subtracting 364 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
91 goes into 560 6 times with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 4484.46
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
91 goes into 140 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 4484.461
The remainder is 49 after subtracting 91 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
490 divided by 91 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4484.4615
Deduct 455 from 490 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
The number 91 fits into 350 3 times, leaving a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 4484.46153
Deduct 273 from 350 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
When dividing 770 by 91, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 4484.461538
Subtracting 728 from 770 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
91 can be fit into 420 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 4484.4615384
Deduct 364 from 420 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
If we divide 560 by 91, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 4484.46153846
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 4484.46153846 with a remainder of 1.4e-08.
