305521 ÷ 16 
We're looking to find how many times 16 goes into 305521.

Step 1:
16 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 16

On to step 2:
30 divided by 16 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 16 from 30 and we're left with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 16

Step 3:
The number 16 fits into 145 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 144 from 145, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 16

Moving on to step 4:
When dividing 15 by 16, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Subtract 0 from 15 to get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 16

Step 5:
The number 16 fits into 152 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 1909.0
The remainder is 8 after subtracting 144 from 152.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 16

Step 6:
16 can be fit into 81 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 19095.0
If we subtract 80 from 81, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 16, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19095.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 16, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 19095.06
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
The number 16 fits into 40 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 19095.062
The remainder is 8 after subtracting 32 from 40.
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:
When dividing 80 by 16, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 19095.0625
Deduct 80 from 80 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.

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: 19095.0625
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.

Going ahead to step 12:
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: 19095.0625
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 quotient of the division is 19095.0625, and the remainder is 0.0.
