We look at the division of 401863 by 16 
We're looking to find how many times 16 goes into 401863.

Step 1:
The number 16 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 16

Moving on to step 2:
40 divided by 16 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 32 from 40 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 16

Going ahead to step 3:
81 divided by 16 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 1 after subtracting 80 from 81.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 16

Moving on to step 4:
18 divided by 16 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 251.0
The remainder is 2 after subtracting 16 from 18.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 16

Going ahead to step 5:
16 can be fit into 26 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 2511.0
Subtract 16 from 26 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 16

Going ahead to step 6:
When dividing 103 by 16, we get 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 25116.0
Deduct 96 from 103 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 16 fits into 70 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 25116.4
If we subtract 64 from 70, 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.

Let's proceed to step 8:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 25116.43
If we take 48 away from 60, we end up 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.

Going ahead to step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
The next digit of our result is 7. 
Result so far: 25116.437
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
16 goes into 80 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 25116.4375
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25116.4375
If we subtract 0 from 0, we 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.

Let's proceed to step 12:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25116.4375
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.

After the division, we end up with 25116.4375 and a remainder of 0.0.
