We're dividing 455011 by 86 
We want to divide 455011 by 86.

Going ahead to step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 86

On to step 2:
If we divide 45 by 86, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 86

Moving on to step 3:
86 can be fit into 455 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 430 away from 455, we end up with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 86

Let's proceed to step 4:
86 can be fit into 250 2 times, resulting in a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 172 from 250 leaves us with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 86

Going ahead to step 5:
The number 86 fits into 781 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 529.0
The remainder is 7 after subtracting 774 from 781.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 86

On to step 6:
71 divided by 86 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 5290.0
If we take 0 away from 71, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
86 can be fit into 710 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 5290.8
If we take 688 away from 710, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
86 goes into 220 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 5290.82
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
86 goes into 480 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5290.825
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
500 divided by 86 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 5290.8255
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 5290.8255, with a leftover of 0.0007.
