We divide 509773 by 91
We want to divide 509773 by 91.

On to step 1:
5 divided by 91 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 91

Step 2:
50 divided by 91 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 91

On to step 3:
When dividing 509 by 91, we get 5 with a remainder of 54.
The next digit of our result is 5. 
Result so far: 5.0
If we take 455 away from 509, we end up with 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 91

Moving on to step 4:
91 can be fit into 547 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we take 546 away from 547, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 91

Step 5:
17 divided by 91 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 560.0
If we subtract 0 from 17, we get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 91

Moving on to step 6:
If we divide 173 by 91, we get 1 and a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 5601.0
Subtract 91 from 173 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 7:
820 divided by 91 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 5601.9
Subtract 819 from 820 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
91 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 5601.9
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 91 fits into 100 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 5601.901
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
91 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 5601.901
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 11:
When dividing 900 by 91, we get 9 with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 5601.90109
If we subtract 819 from 900, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 12:
91 can be fit into 810 8 times, resulting in a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 5601.901098
The remainder is 82 after subtracting 728 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 13:
91 can be fit into 820 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 5601.9010989
If we take 819 away from 820, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 14:
91 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 5601.9010989
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 5601.9010989 with a remainder of 1e-08.
