We look at the division of 393258 by 53 
Our goal is to divide 393258 by 53.

Advancing to step 1:
53 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 53

Advancing to step 2:
53 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 53

Going ahead to step 3:
53 can be fit into 393 7 times, resulting in a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 22 after subtracting 371 from 393.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 53

Advancing to step 4:
The number 53 fits into 222 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we take 212 away from 222, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 53

Going ahead to step 5:
53 goes into 105 1 times with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 741.0
The remainder is 52 after subtracting 53 from 105.
Fetch the next digit (8) from the dividend, attach it to 52 and continue: 528 / 53

Step 6:
If we divide 528 by 53, we get 9 and a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 7419.0
If we subtract 477 from 528, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
53 goes into 510 9 times with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 7419.9
Deduct 477 from 510 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
53 goes into 330 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 7419.96
The remainder is 12 after subtracting 318 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 53 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 7419.962
Subtracting 106 from 120 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
The number 53 fits into 140 2 times, leaving a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 7419.9622
If we take 106 away from 140, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 7419.9622 with a remainder of 0.00034.
