We look at the division of 48571911 by 86 
We want to divide 48571911 by 86.

Going ahead to step 1:
86 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 86

Going ahead to step 2:
When dividing 48 by 86, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 86

Going ahead to step 3:
485 divided by 86 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 430 from 485 and we're left with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 86

Advancing to step 4:
The number 86 fits into 557 6 times, leaving a remainder of 41.
The next digit of our result is 6. 
Result so far: 56.0
If we take 516 away from 557, we end up with 41.
Fetch the next digit (1) from the dividend, attach it to 41 and continue: 411 / 86

Step 5:
86 can be fit into 411 4 times, resulting in a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 564.0
If we take 344 away from 411, we end up with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 86

Moving on to step 6:
86 can be fit into 679 7 times, resulting in a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 5647.0
Deduct 602 from 679 and we're left with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 86

Let's proceed to step 7:
86 can be fit into 771 8 times, resulting in a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 56478.0
Subtract 688 from 771 to get 83.
Grab the next digit (1) from the dividend, add it to 83, then carry on: 831 / 86

Advancing to step 8:
The number 86 fits into 831 9 times, leaving a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 564789.0
The remainder is 57 after subtracting 774 from 831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
When dividing 570 by 86, we get 6 with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 564789.6
If we subtract 516 from 570, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
86 can be fit into 540 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 564789.66
Subtracting 516 from 540 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 564789.66, with a leftover of 0.024.
