We're dividing 393455 by 63 
We want to figure out the number of times 393455 can be divided by 63.

Advancing to step 1:
63 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 take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 63

Let's proceed to step 2:
When dividing 39 by 63, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 63

Moving on to step 3:
The number 63 fits into 393 6 times, leaving a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 378 away from 393, we end up with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 63

Moving on to step 4:
When dividing 154 by 63, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we subtract 126 from 154, we get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 63

Let's proceed to step 5:
285 divided by 63 is 4 with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 624.0
The remainder is 33 after subtracting 252 from 285.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 63

On to step 6:
If we divide 335 by 63, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 6245.0
If we take 315 away from 335, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 63 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 6245.3
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
110 divided by 63 is 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 6245.31
If we subtract 63 from 110, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
The number 63 fits into 470 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 6245.317
The remainder is 29 after subtracting 441 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
If we divide 290 by 63, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 6245.3174
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
When dividing 380 by 63, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6245.31746
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
When dividing 20 by 63, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 6245.31746
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 63, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 6245.3174603
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
63 goes into 110 1 times with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 6245.31746031
The remainder is 47 after subtracting 63 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 6245.31746031 and a remainder of 4.7e-08.
