We look at the division of 400963 by 4 
Our goal is to divide 400963 by 4.

Let's proceed to step 1:
4 can be fit into 4 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 4 from 4, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 4

Going ahead to step 2:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

On to step 3:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 4

Going ahead to step 4:
If we divide 9 by 4, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1002.0
If we take 8 away from 9, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 4

On to step 5:
4 goes into 16 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 10024.0
The remainder is 0 after subtracting 16 from 16.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 4

Step 6:
The number 4 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 100240.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 100240.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 100240.75
Deduct 20 from 20 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100240.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100240.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 100240.75, and the remainder is 0.0.
