We're dividing 580230 by 91 
Let's see how many times 91 fits into 580230.

Going ahead 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
If we take 0 away from 5, we end up with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 91

Going ahead to step 2:
91 goes into 58 0 times with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 91

Going ahead to step 3:
91 goes into 580 6 times with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 546 from 580 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 91

Let's proceed to step 4:
When dividing 342 by 91, we get 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 273 from 342 to get 69.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 91

Moving on to step 5:
If we divide 693 by 91, we get 7 and a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 637.0
The remainder is 56 after subtracting 637 from 693.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 91

On to step 6:
91 goes into 560 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 6376.0
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
91 can be fit into 140 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 6376.1
If we take 91 away from 140, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
91 goes into 490 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 6376.15
If we take 455 away from 490, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
91 can be fit into 350 3 times, resulting in a remainder of 77.
The next digit of our result is 3. 
Result so far: 6376.153
If we take 273 away from 350, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
The number 91 fits into 770 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 6376.1538
If we subtract 728 from 770, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
If we divide 420 by 91, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 6376.15384
If we subtract 364 from 420, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
The number 91 fits into 560 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 6376.153846
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
When dividing 140 by 91, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 6376.1538461
Subtracting 91 from 140 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 14:
490 divided by 91 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 6376.15384615
Deduct 455 from 490 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 6376.15384615 with a remainder of 3.5e-08.
