805459 ÷ 91 
Let's see how many times 91 fits into 805459.

Step 1:
8 divided by 91 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 91

On to step 2:
91 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 91

Advancing to step 3:
The number 91 fits into 805 8 times, leaving a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 728 away from 805, we end up with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 91

Going ahead to step 4:
91 can be fit into 774 8 times, resulting in a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 88.0
Deduct 728 from 774 and we're left with 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 91

On to step 5:
When dividing 465 by 91, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 885.0
Deduct 455 from 465 and we're left with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 91

Advancing to step 6:
If we divide 109 by 91, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 8851.0
If we subtract 91 from 109, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
91 can be fit into 180 1 times, resulting in a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 8851.1
If we take 91 away from 180, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 8:
91 goes into 890 9 times with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 8851.19
Deduct 819 from 890 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
91 can be fit into 710 7 times, resulting in a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 8851.197
If we take 637 away from 710, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
91 can be fit into 730 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8851.1978
If we subtract 728 from 730, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
The number 91 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8851.1978
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
200 divided by 91 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 8851.197802
Subtracting 182 from 200 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
When dividing 180 by 91, we get 1 with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 8851.1978021
Subtract 91 from 180 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 14:
91 goes into 890 9 times with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 8851.19780219
Deduct 819 from 890 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 8851.19780219 with a remaining 7.1e-08.
