868789 ÷ 16 
We want to figure out the number of times 868789 can be divided by 16.

On to step 1:
When dividing 8 by 16, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 16

Step 2:
16 goes into 86 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 80 from 86 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 16

Let's proceed to step 3:
The number 16 fits into 68 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 54.0
The remainder is 4 after subtracting 64 from 68.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 16

Step 4:
The number 16 fits into 47 2 times, leaving a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 542.0
Deduct 32 from 47 and we're left with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 16

On to step 5:
The number 16 fits into 158 9 times, leaving a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 5429.0
If we subtract 144 from 158, we get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 16

Going ahead to step 6:
16 can be fit into 149 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 54299.0
The remainder is 5 after subtracting 144 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 16, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 54299.3
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.

Let's proceed to step 8:
If we divide 20 by 16, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 54299.31
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 54299.312
If we subtract 32 from 40, 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.

Let's proceed to step 10:
80 divided by 16 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 54299.3125
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.

Let's proceed to step 11:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 54299.3125
Subtract 0 from 0 to 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.

Step 12:
16 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54299.3125
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 54299.3125, and the remainder is 0.0.
