457817 ÷ 91 
Let's see how many times 91 fits into 457817.

Going ahead to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 91

Advancing to step 2:
When dividing 45 by 91, we get 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 91

Moving on to step 3:
If we divide 457 by 91, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 455 from 457 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 91

Going ahead to step 4:
If we divide 28 by 91, we get 0 and a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 91

Advancing to step 5:
When dividing 281 by 91, we get 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 503.0
Deduct 273 from 281 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 91

On to step 6:
91 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 5030.0
Subtracting 0 from 87 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 7:
When dividing 870 by 91, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 5030.9
If we subtract 819 from 870, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
91 can be fit into 510 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 5030.95
If we subtract 455 from 510, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
550 divided by 91 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 5030.956
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
91 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 5030.956
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 91, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 5030.95604
If we take 364 away from 400, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
If we divide 360 by 91, we get 3 and a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 5030.956043
Subtracting 273 from 360 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
870 divided by 91 is 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 5030.9560439
If we take 819 away from 870, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
91 goes into 510 5 times with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 5030.95604395
Subtracting 455 from 510 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 5030.95604395 with a remaining 5.5e-08.
