We look at the division of 393486 by 63 
Let's see how many times 63 fits into 393486.

On to step 1:
3 divided by 63 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 63

Advancing to step 2:
If we divide 39 by 63, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 63

Let's proceed to step 3:
The number 63 fits into 393 6 times, leaving a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 15 after subtracting 378 from 393.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 63

On to step 4:
154 divided by 63 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 28 after subtracting 126 from 154.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 63

Advancing to step 5:
If we divide 288 by 63, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 624.0
Subtract 252 from 288 to get 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 63

Advancing to step 6:
366 divided by 63 is 5 with a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 6245.0
Subtracting 315 from 366 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
63 can be fit into 510 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 6245.8
If we take 504 away from 510, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 63, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 6245.8
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
63 can be fit into 600 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 6245.809
Subtract 567 from 600 to get 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 10:
If we divide 330 by 63, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6245.8095
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
The number 63 fits into 150 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 6245.80952
If we subtract 126 from 150, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
240 divided by 63 is 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 6245.809523
Deduct 189 from 240 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 13:
When dividing 510 by 63, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 6245.8095238
If we take 504 away from 510, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
When dividing 60 by 63, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 6245.8095238
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 6245.8095238 with a remainder of 6e-08.
