559991 ÷ 16 
We want to divide 559991 by 16.

Let's proceed to step 1:
The number 16 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 16

Advancing to step 2:
The number 16 fits into 55 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 48 from 55 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 16

Advancing to step 3:
16 goes into 79 4 times with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 64 from 79 and we're left with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 16

Step 4:
If we divide 159 by 16, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 349.0
Deduct 144 from 159 and we're left with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 16

Going ahead to step 5:
159 divided by 16 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 3499.0
If we take 144 away from 159, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 16

Going ahead to step 6:
16 can be fit into 151 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 34999.0
Subtract 144 from 151 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 16 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 34999.4
Subtract 64 from 70 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:
16 can be fit into 60 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 34999.43
Subtracting 48 from 60 leaves us 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.

On to step 9:
120 divided by 16 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 34999.437
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.

Advancing to step 10:
16 goes into 80 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 34999.4375
Subtracting 80 from 80 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.

Let's proceed to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 34999.4375
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.

Advancing to step 12:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34999.4375
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.

In conclusion, the division gives 34999.4375 with a balance of 0.0.
