We look at the division of 53863 by 9 
Let's see how many times 9 fits into 53863.

Let's proceed to step 1:
5 divided by 9 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 9

Step 2:
When dividing 53 by 9, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 45 away from 53, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 9

On to step 3:
When dividing 88 by 9, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtracting 81 from 88 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 9

Moving on to step 4:
If we divide 76 by 9, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 598.0
The remainder is 4 after subtracting 72 from 76.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

On to step 5:
9 goes into 43 4 times with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 5984.0
If we subtract 36 from 43, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
70 divided by 9 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 5984.7
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
70 divided by 9 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 5984.77
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 5984.77 with a remainder of 0.007.
