508809 divided by 91 
We're looking to find how many times 91 goes into 508809.

On to step 1:
When dividing 5 by 91, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 91

Moving on to step 2:
50 divided by 91 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 91

Step 3:
If we divide 508 by 91, we get 5 and a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 455 from 508 to get 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 91

Let's proceed to step 4:
538 divided by 91 is 5 with a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 455 from 538 and we're left with 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 91

On to step 5:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 559.0
If we take 819 away from 830, we end up with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 91

Advancing to step 6:
When dividing 119 by 91, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 5591.0
Subtract 91 from 119 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
When dividing 280 by 91, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 5591.3
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
70 divided by 91 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 5591.3
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
The number 91 fits into 700 7 times, leaving a remainder of 63.
The next digit of our result is 7. 
Result so far: 5591.307
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 10:
If we divide 630 by 91, we get 6 and a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 5591.3076
Deduct 546 from 630 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
91 can be fit into 840 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 5591.30769
The remainder is 21 after subtracting 819 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
If we divide 210 by 91, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 5591.307692
Subtract 182 from 210 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
If we divide 280 by 91, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 5591.3076923
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
70 divided by 91 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 5591.3076923
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 5591.3076923, with a leftover of 7e-08.
