Let's divide 510240 by 91
We're looking to find how many times 91 goes into 510240.

Let's proceed to 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
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 91

On to step 2:
91 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 91

Let's proceed to step 3:
When dividing 510 by 91, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 455 from 510, we get 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 91

Let's proceed to step 4:
The number 91 fits into 552 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we subtract 546 from 552, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 91

Let's proceed to step 5:
If we divide 64 by 91, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 560.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 91

Advancing to step 6:
640 divided by 91 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 5607.0
The remainder is 3 after subtracting 637 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
91 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 5607.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
91 can be fit into 300 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 5607.03
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
270 divided by 91 is 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 5607.032
If we subtract 182 from 270, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
If we divide 880 by 91, we get 9 and a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 5607.0329
Subtracting 819 from 880 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
When dividing 610 by 91, we get 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 5607.03296
The remainder is 64 after subtracting 546 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
When dividing 640 by 91, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 5607.032967
Subtracting 637 from 640 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
91 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5607.032967
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
91 can be fit into 300 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 5607.03296703
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 5607.03296703 and a remainder of 2.7e-08.
