86356005 ÷ 580 
We're looking to find how many times 580 goes into 86356005.

On to step 1:
8 divided by 580 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 580

Moving on to step 2:
580 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 580

Advancing to step 3:
When dividing 863 by 580, we get 1 with a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 580 from 863, we get 283.
Append the next digit (5) from the dividend to 283 and continue with: 2835 / 580

Advancing to step 4:
580 can be fit into 2835 4 times, resulting in a remainder of 515.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 2320 from 2835 leaves us with 515.
Include the next digit (6) from the dividend after 515, then repeat: 5156 / 580

Moving on to step 5:
5156 divided by 580 is 8 with a remainder of 516.
Put 8 as the next digit of the answer. 
Result so far: 148.0
If we subtract 4640 from 5156, we get 516.
Take the next digit (0) from the dividend and append it to 516, then repeat: 5160 / 580

Let's proceed to step 6:
The number 580 fits into 5160 8 times, leaving a remainder of 520.
The next digit of our result is 8. 
Result so far: 1488.0
If we subtract 4640 from 5160, we get 520.
Grab the next digit (0) from the dividend, add it to 520, then carry on: 5200 / 580

Moving on to step 7:
5200 divided by 580 is 8 with a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 14888.0
Deduct 4640 from 5200 and we're left with 560.
Append the next digit (5) from the dividend to 560 and continue with: 5605 / 580

Going ahead to step 8:
580 goes into 5605 9 times with a remainder of 385.
Put 9 as the next digit of the answer. 
Result so far: 148889.0
Subtract 5220 from 5605 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 9:
3850 divided by 580 is 6 with a remainder of 370.
Write down 6 as next digit of the result. 
Result so far: 148889.6
If we subtract 3480 from 3850, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 10:
When dividing 3700 by 580, we get 6 with a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 148889.66
Deduct 3480 from 3700 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Our division results in 148889.66 with a remaining 0.22.
