We're dividing 406740 by 16 
Our goal is to divide 406740 by 16.

Going ahead to step 1:
The number 16 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 16

On to step 2:
When dividing 40 by 16, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 32 from 40 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 16

On to step 3:
When dividing 86 by 16, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 80 from 86, we get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 16

Let's proceed to step 4:
16 can be fit into 67 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 254.0
If we take 64 away from 67, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 16

Step 5:
16 goes into 34 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2542.0
If we take 32 away from 34, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 16

Going ahead to step 6:
If we divide 20 by 16, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 25421.0
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
16 goes into 40 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 25421.2
Deduct 32 from 40 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

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: 25421.25
If we subtract 80 from 80, 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.

Step 9:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25421.25
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.

Going ahead to step 10:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25421.25
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.

The quotient of the division is 25421.25, and the remainder is 0.0.
