We're dividing 400665 by 63 
We're looking to find how many times 63 goes into 400665.

Step 1:
When dividing 4 by 63, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 63

Going ahead to step 2:
40 divided by 63 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 63

Step 3:
63 can be fit into 400 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 22 after subtracting 378 from 400.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 63

On to step 4:
63 goes into 226 3 times with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Deduct 189 from 226 and we're left with 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 63

Step 5:
63 can be fit into 376 5 times, resulting in a remainder of 61.
Put 5 as the next digit of the answer. 
Result so far: 635.0
If we subtract 315 from 376, we get 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 63

Moving on to step 6:
The number 63 fits into 615 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 6359.0
If we take 567 away from 615, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
The number 63 fits into 480 7 times, leaving a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 6359.7
If we subtract 441 from 480, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
63 can be fit into 390 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6359.76
Deduct 378 from 390 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 63 is 1 with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 6359.761
Deduct 63 from 120 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
When dividing 570 by 63, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 6359.7619
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
The number 63 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 6359.7619
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
300 divided by 63 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 6359.761904
The remainder is 48 after subtracting 252 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
The number 63 fits into 480 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 6359.7619047
Deduct 441 from 480 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 14:
390 divided by 63 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6359.76190476
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 6359.76190476, with a leftover of 1.2e-08.
