Let's divide 509169 by 91
Let's see how many times 91 fits into 509169.

Step 1:
91 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 91

Moving on to step 2:
If we divide 50 by 91, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 91

Moving on to step 3:
91 can be fit into 509 5 times, resulting in a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 455 from 509 to get 54.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 91

Going ahead to step 4:
91 can be fit into 541 5 times, resulting in a remainder of 86.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtract 455 from 541 to get 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 91

Advancing to step 5:
If we divide 866 by 91, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 559.0
Subtracting 819 from 866 leaves us with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 91

Let's proceed to step 6:
The number 91 fits into 479 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 5595.0
If we take 455 away from 479, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
240 divided by 91 is 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 5595.2
Deduct 182 from 240 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
580 divided by 91 is 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 5595.26
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
340 divided by 91 is 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 5595.263
The remainder is 67 after subtracting 273 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 10:
If we divide 670 by 91, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 5595.2637
Subtracting 637 from 670 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
If we divide 330 by 91, we get 3 and a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 5595.26373
The remainder is 57 after subtracting 273 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
The number 91 fits into 570 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 5595.263736
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
When dividing 240 by 91, we get 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 5595.2637362
Deduct 182 from 240 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
When dividing 580 by 91, we get 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 5595.26373626
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 5595.26373626 with a remainder of 3.4e-08.
