86448569 ÷ 580 
Our goal is to divide 86448569 by 580.

Moving on to step 1:
The number 580 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 580

Advancing 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
If we take 0 away from 86, we end up with 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 580

On to step 3:
If we divide 864 by 580, we get 1 and a remainder of 284.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 580 from 864 leaves us with 284.
Include the next digit (4) from the dividend after 284, then repeat: 2844 / 580

Let's proceed to step 4:
2844 divided by 580 is 4 with a remainder of 524.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2320 from 2844 and we're left with 524.
Append the next digit (8) from the dividend to 524 and continue with: 5248 / 580

Step 5:
When dividing 5248 by 580, we get 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
Subtracting 5220 from 5248 leaves us with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 580

On to step 6:
580 can be fit into 285 0 times, resulting in a remainder of 285.
The number 0 becomes the next digit in our result. 
Result so far: 1490.0
Subtracting 0 from 285 leaves us with 285.
Include the next digit (6) from the dividend after 285, then repeat: 2856 / 580

Going ahead to step 7:
The number 580 fits into 2856 4 times, leaving a remainder of 536.
Write down 4 as next digit of the result. 
Result so far: 14904.0
Subtracting 2320 from 2856 leaves us with 536.
Append the next digit (9) from the dividend to 536 and continue with: 5369 / 580

Going ahead to step 8:
The number 580 fits into 5369 9 times, leaving a remainder of 149.
The next digit of our result is 9. 
Result so far: 149049.0
Subtracting 5220 from 5369 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 9:
When dividing 1490 by 580, we get 2 with a remainder of 330.
Write down 2 as next digit of the result. 
Result so far: 149049.2
Subtracting 1160 from 1490 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
3300 divided by 580 is 5 with a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 149049.25
The remainder is 400 after subtracting 2900 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
4000 divided by 580 is 6 with a remainder of 520.
Put 6 as the next digit of the answer. 
Result so far: 149049.256
Deduct 3480 from 4000 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
580 goes into 5200 8 times with a remainder of 560.
The next digit of our result is 8. 
Result so far: 149049.2568
Subtracting 4640 from 5200 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
When dividing 5600 by 580, we get 9 with a remainder of 380.
Put 9 as the next digit of the answer. 
Result so far: 149049.25689
Subtract 5220 from 5600 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
580 goes into 3800 6 times with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 149049.256896
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.

Let's proceed to step 15:
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: 149049.2568965
Subtract 2900 from 3200 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 16:
580 can be fit into 3000 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 149049.25689655
The remainder is 100 after subtracting 2900 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 149049.25689655 and a remainder of 1e-07.
