We divide 403040 by 16
We want to divide 403040 by 16.

On to step 1:
16 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 16

Advancing to step 2:
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: 2.0
The remainder is 8 after subtracting 32 from 40.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 16

Advancing to step 3:
If we divide 83 by 16, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 25.0
If we take 80 away from 83, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 16

Advancing to step 4:
30 divided by 16 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 251.0
If we subtract 16 from 30, we get 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 16

On to step 5:
When dividing 144 by 16, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 2519.0
Deduct 144 from 144 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 16

Let's proceed to step 6:
When dividing 0 by 16, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25190.0
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.

Let's proceed to step 7:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25190.0
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.

Let's proceed to step 8:
If we divide 0 by 16, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25190.0
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.

Our division results in 25190.0 with a remaining 0.0.
