We're dividing 456736 by 86 
We want to divide 456736 by 86.

Step 1:
4 divided by 86 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 86

On to step 2:
86 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 86

Moving on to step 3:
86 goes into 456 5 times with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 430 from 456 and we're left with 26.
Grab the next digit (7) from the dividend, add it to 26, then carry on: 267 / 86

On to step 4:
86 can be fit into 267 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 53.0
If we take 258 away from 267, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 86

On to step 5:
When dividing 93 by 86, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 531.0
The remainder is 7 after subtracting 86 from 93.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 86

Advancing to step 6:
When dividing 76 by 86, we get 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 5310.0
If we take 0 away from 76, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 7:
If we divide 760 by 86, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 5310.8
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 8:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 5310.88
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 5310.88 with a remainder of 0.032.
