86923304 ÷ 580 
We're looking to find how many times 580 goes into 86923304.

Moving on to step 1:
If we divide 8 by 580, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 580

Moving on to step 2:
The number 580 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 580

Going ahead to step 3:
The number 580 fits into 869 1 times, leaving a remainder of 289.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 580 from 869, we get 289.
Bring next digit (2) of the dividend behind the 289 and repeat the process: 2892 / 580

On to step 4:
The number 580 fits into 2892 4 times, leaving a remainder of 572.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 572 after subtracting 2320 from 2892.
Fetch the next digit (3) from the dividend, attach it to 572 and continue: 5723 / 580

On to step 5:
580 can be fit into 5723 9 times, resulting in a remainder of 503.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
Deduct 5220 from 5723 and we're left with 503.
Take the next digit (3) from the dividend and append it to 503, then repeat: 5033 / 580

Advancing to step 6:
When dividing 5033 by 580, we get 8 with a remainder of 393.
The number 8 becomes the next digit in our result. 
Result so far: 1498.0
Subtracting 4640 from 5033 leaves us with 393.
Fetch the next digit (0) from the dividend, attach it to 393 and continue: 3930 / 580

Going ahead to step 7:
3930 divided by 580 is 6 with a remainder of 450.
The next digit of our result is 6. 
Result so far: 14986.0
The remainder is 450 after subtracting 3480 from 3930.
Bring next digit (4) of the dividend behind the 450 and repeat the process: 4504 / 580

Step 8:
580 goes into 4504 7 times with a remainder of 444.
The number 7 becomes the next digit in our result. 
Result so far: 149867.0
The remainder is 444 after subtracting 4060 from 4504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 9:
4440 divided by 580 is 7 with a remainder of 380.
Write down 7 as next digit of the result. 
Result so far: 149867.7
Deduct 4060 from 4440 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 10:
580 goes into 3800 6 times with a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 149867.76
If we take 3480 away from 3800, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 11:
If we divide 3200 by 580, we get 5 and a remainder of 300.
The next digit of our result is 5. 
Result so far: 149867.765
The remainder is 300 after subtracting 2900 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
The number 580 fits into 3000 5 times, leaving a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 149867.7655
If we subtract 2900 from 3000, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 149867.7655 with a remainder of 0.001.
