We look at the division of 422755 by 86 
We're looking to find how many times 86 goes into 422755.

Going ahead to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 86

Step 2:
If we divide 42 by 86, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 86

Step 3:
If we divide 422 by 86, we get 4 and a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 78 after subtracting 344 from 422.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 86

Going ahead to step 4:
When dividing 787 by 86, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we subtract 774 from 787, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 86

Step 5:
135 divided by 86 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 491.0
If we subtract 86 from 135, we get 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 86

Let's proceed to step 6:
When dividing 495 by 86, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 4915.0
If we take 430 away from 495, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
650 divided by 86 is 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 4915.7
Subtracting 602 from 650 leaves us with 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 8:
If we divide 480 by 86, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4915.75
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.

Moving on to step 9:
86 goes into 500 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 4915.755
The remainder is 70 after subtracting 430 from 500.
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 result is 4915.755 with a remainder of 0.007.
