We divide 400023 by 63
We want to figure out the number of times 400023 can be divided by 63.

Advancing to step 1:
4 divided by 63 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 63

On to step 2:
If we divide 40 by 63, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 63

On to step 3:
63 goes into 400 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 378 from 400 leaves us with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 63

Step 4:
63 can be fit into 220 3 times, resulting in a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Subtract 189 from 220 to get 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 63

On to step 5:
If we divide 312 by 63, we get 4 and a remainder of 60.
The next digit of our result is 4. 
Result so far: 634.0
Subtracting 252 from 312 leaves us with 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 63

Moving on to step 6:
The number 63 fits into 603 9 times, leaving a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 6349.0
Subtract 567 from 603 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
63 can be fit into 360 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 6349.5
The remainder is 45 after subtracting 315 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
The number 63 fits into 450 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 6349.57
If we take 441 away from 450, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
90 divided by 63 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 6349.571
Subtracting 63 from 90 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
If we divide 270 by 63, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 6349.5714
Subtract 252 from 270 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
The number 63 fits into 180 2 times, leaving a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 6349.57142
If we take 126 away from 180, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
When dividing 540 by 63, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 6349.571428
Subtracting 504 from 540 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
63 goes into 360 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 6349.5714285
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
63 goes into 450 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 6349.57142857
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 6349.57142857, and the remainder is 9e-09.
