Let's divide 903903 by 16
Our goal is to divide 903903 by 16.

Going ahead to step 1:
The number 16 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 16

On to step 2:
When dividing 90 by 16, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 80 away from 90, we end up with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 16

Let's proceed to step 3:
16 can be fit into 103 6 times, resulting in a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 96 from 103 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 16

On to step 4:
When dividing 79 by 16, we get 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 564.0
Subtracting 64 from 79 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 16

On to step 5:
16 can be fit into 150 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 5649.0
Subtracting 144 from 150 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 16

Step 6:
16 can be fit into 63 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 56493.0
If we subtract 48 from 63, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
16 goes into 150 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 56493.9
Subtract 144 from 150 to 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.

Step 8:
If we divide 60 by 16, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 56493.93
Deduct 48 from 60 and we're left 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.

Moving on to step 9:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 56493.937
If we subtract 112 from 120, we 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:
If we divide 80 by 16, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 56493.9375
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.

Moving on to step 11:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 56493.9375
The remainder is 0 after subtracting 0 from 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:
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: 56493.9375
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.

The final result is 56493.9375 with a remainder of 0.0.
