873558 ÷ 16 
We want to divide 873558 by 16.

Going ahead to step 1:
16 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 16

Moving on to step 2:
When dividing 87 by 16, we get 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 80 from 87 to get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 16

Going ahead to step 3:
73 divided by 16 is 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 64 from 73 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 16

Let's proceed to step 4:
16 goes into 95 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 545.0
If we take 80 away from 95, we end up with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 16

Step 5:
The number 16 fits into 155 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 5459.0
Subtracting 144 from 155 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 16

On to step 6:
If we divide 118 by 16, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 54597.0
If we subtract 112 from 118, we 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.

Let's proceed to step 7:
If we divide 60 by 16, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 54597.3
The remainder is 12 after subtracting 48 from 60.
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 8:
16 can be fit into 120 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 54597.37
If we take 112 away from 120, 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.

On to step 9:
80 divided by 16 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 54597.375
If we take 80 away from 80, 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.

On to step 10:
16 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 54597.375
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.

Going ahead to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 54597.375
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.

The final result is 54597.375 with a remainder of 0.0.
