We divide 864851 by 16
We're looking to find how many times 16 goes into 864851.

On to step 1:
8 divided by 16 is 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.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 16

Moving on to step 2:
86 divided by 16 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 80 from 86 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 16

Advancing to step 3:
64 divided by 16 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 54.0
If we take 64 away from 64, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 16

On to step 4:
When dividing 8 by 16, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 540.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 16

Step 5:
85 divided by 16 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5405.0
Subtract 80 from 85 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 16

On to step 6:
16 can be fit into 51 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 54053.0
Subtract 48 from 51 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
16 goes into 30 1 times with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 54053.1
Deduct 16 from 30 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
16 goes into 140 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 54053.18
If we subtract 128 from 140, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 16, we get 7 and a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 54053.187
Subtract 112 from 120 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.

On to step 10:
When dividing 80 by 16, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 54053.1875
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.

Moving on to step 11:
If we divide 0 by 16, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 54053.1875
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.

Let's proceed to step 12:
0 divided by 16 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 54053.1875
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.

Our division results in 54053.1875 with a remaining 0.0.
