518985 ÷ 91 
Let's see how many times 91 fits into 518985.

Going ahead to step 1:
If we divide 5 by 91, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 91

Going ahead to step 2:
When dividing 51 by 91, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 91

Let's proceed to step 3:
When dividing 518 by 91, we get 5 with a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 63 after subtracting 455 from 518.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 91

Step 4:
91 can be fit into 639 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 57.0
Deduct 637 from 639 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 91

Moving on to step 5:
28 divided by 91 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 570.0
If we subtract 0 from 28, we get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 91

Let's proceed to step 6:
If we divide 285 by 91, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 5703.0
If we take 273 away from 285, we end up 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.

On to step 7:
91 can be fit into 120 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 5703.1
Subtract 91 from 120 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
When dividing 290 by 91, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 5703.13
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
91 goes into 170 1 times with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 5703.131
The remainder is 79 after subtracting 91 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 10:
91 can be fit into 790 8 times, resulting in a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 5703.1318
Deduct 728 from 790 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 11:
When dividing 620 by 91, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 5703.13186
Subtracting 546 from 620 leaves us 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 12:
91 can be fit into 740 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5703.131868
If we take 728 away from 740, we end up 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.

Let's proceed to step 13:
120 divided by 91 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 5703.1318681
Subtracting 91 from 120 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
The number 91 fits into 290 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 5703.13186813
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.

Our division results in 5703.13186813 with a remaining 1.7e-08.
