We're dividing 399723 by 63 
Let's see how many times 63 fits into 399723.

On to step 1:
63 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in 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

Step 2:
39 divided by 63 is 0 with 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.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 63

On to step 3:
If we divide 399 by 63, we get 6 and a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 378 from 399 to get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 63

Let's proceed to step 4:
If we divide 217 by 63, we get 3 and a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 189 from 217 to get 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 63

Going ahead to step 5:
If we divide 282 by 63, we get 4 and a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 634.0
If we subtract 252 from 282, we get 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 63

On to step 6:
When dividing 303 by 63, we get 4 with a remainder of 51.
The next digit of our result is 4. 
Result so far: 6344.0
Subtract 252 from 303 to 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:
The number 63 fits into 510 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 6344.8
Subtract 504 from 510 to get 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 8:
63 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 6344.8
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
If we divide 600 by 63, we get 9 and a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 6344.809
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.

Step 10:
When dividing 330 by 63, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 6344.8095
Subtracting 315 from 330 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
If we divide 150 by 63, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 6344.80952
The remainder is 24 after subtracting 126 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
63 goes into 240 3 times with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 6344.809523
Subtracting 189 from 240 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.

Going ahead to step 13:
63 can be fit into 510 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 6344.8095238
If we subtract 504 from 510, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
When dividing 60 by 63, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 6344.8095238
If we take 0 away from 60, we end up with 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 6344.8095238 with a remainder of 6e-08.
