402548 divided by 16 
Let's see how many times 16 fits into 402548.

Advancing to step 1:
If we divide 4 by 16, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 16

On to step 2:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 8 after subtracting 32 from 40.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 16

Let's proceed to step 3:
The number 16 fits into 82 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 2 after subtracting 80 from 82.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 16

Step 4:
When dividing 25 by 16, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
Subtracting 16 from 25 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 16

Moving on to step 5:
94 divided by 16 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 2515.0
Subtract 80 from 94 to get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 16

Advancing to step 6:
When dividing 148 by 16, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 25159.0
If we take 144 away from 148, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 25159.2
Subtract 32 from 40 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 8:
16 can be fit into 80 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25159.25
Subtracting 80 from 80 leaves us 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:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25159.25
Deduct 0 from 0 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.

On to step 10:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25159.25
Subtracting 0 from 0 leaves us 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 25159.25 and a remainder of 0.0.
