We're dividing 405838 by 91 
We want to divide 405838 by 91.

Going ahead to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 91

On to step 2:
91 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 91

Let's proceed to step 3:
91 goes into 405 4 times with a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 41 after subtracting 364 from 405.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 91

Advancing to step 4:
91 can be fit into 418 4 times, resulting in a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Subtract 364 from 418 to get 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 91

Going ahead to step 5:
91 can be fit into 543 5 times, resulting in a remainder of 88.
Write down 5 as next digit of the result. 
Result so far: 445.0
The remainder is 88 after subtracting 455 from 543.
Include the next digit (8) from the dividend after 88, then repeat: 888 / 91

Moving on to step 6:
91 can be fit into 888 9 times, resulting in a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 4459.0
The remainder is 69 after subtracting 819 from 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
91 can be fit into 690 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 4459.7
Subtracting 637 from 690 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 8:
530 divided by 91 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4459.75
The remainder is 75 after subtracting 455 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
91 goes into 750 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 4459.758
Subtracting 728 from 750 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
220 divided by 91 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 4459.7582
If we take 182 away from 220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
91 goes into 380 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 4459.75824
The remainder is 16 after subtracting 364 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 91 is 1 with a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 4459.758241
Subtracting 91 from 160 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 13:
When dividing 690 by 91, we get 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 4459.7582417
If we take 637 away from 690, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 14:
The number 91 fits into 530 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 4459.75824175
The remainder is 75 after subtracting 455 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 4459.75824175 and a remainder of 7.5e-08.
