303189 ÷ 16 
Our goal is to divide 303189 by 16.

Let's proceed to step 1:
When dividing 3 by 16, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 16

Going ahead to step 2:
If we divide 30 by 16, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 16 from 30, we get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 16

Advancing to step 3:
The number 16 fits into 143 8 times, leaving a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 128 from 143, we get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 16

Step 4:
151 divided by 16 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
Subtracting 144 from 151 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 16

Let's proceed to step 5:
If we divide 78 by 16, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 1894.0
Deduct 64 from 78 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 16

Going ahead to step 6:
149 divided by 16 is 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 18949.0
Deduct 144 from 149 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 16 fits into 50 3 times, leaving a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 18949.3
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 16 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 18949.31
If we take 16 away from 20, 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.

Advancing to step 9:
If we divide 40 by 16, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 18949.312
If we take 32 away from 40, we end up 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.

Advancing to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 18949.3125
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.

Going ahead to step 11:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18949.3125
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.

Step 12:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18949.3125
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 18949.3125, and the remainder is 0.0.
