We divide 871985 by 16
We're looking to find how many times 16 goes into 871985.

Going ahead to step 1:
If we divide 8 by 16, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 16

Going ahead to step 2:
16 can be fit into 87 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 7 after subtracting 80 from 87.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 16

Let's proceed to step 3:
The number 16 fits into 71 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 64 from 71 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 16

Advancing to step 4:
16 can be fit into 79 4 times, resulting in a remainder of 15.
The next digit of our result is 4. 
Result so far: 544.0
Subtract 64 from 79 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 16

Step 5:
If we divide 158 by 16, we get 9 and a remainder of 14.
The next digit of our result is 9. 
Result so far: 5449.0
Subtract 144 from 158 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 16

Let's proceed to step 6:
When dividing 145 by 16, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 54499.0
If we take 144 away from 145, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
16 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 54499.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 16, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 54499.06
If we subtract 96 from 100, we 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.

On to step 9:
40 divided by 16 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 54499.062
Subtract 32 from 40 to 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:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 54499.0625
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.

Let's proceed to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 54499.0625
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.

On to step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54499.0625
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.

The final outcome is 54499.0625, with a leftover of 0.0.
