We divide 51857 by 16
We want to divide 51857 by 16.

Step 1:
16 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 16

Step 2:
The number 16 fits into 51 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 48 away from 51, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 16

On to step 3:
The number 16 fits into 38 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 32 from 38 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 16

Advancing to step 4:
65 divided by 16 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 324.0
Subtract 64 from 65 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 16

Going ahead to step 5:
17 divided by 16 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 3241.0
If we subtract 16 from 17, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 6:
The number 16 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3241.0
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.

Step 7:
100 divided by 16 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 3241.06
Subtracting 96 from 100 leaves us with 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 8:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3241.062
Deduct 32 from 40 and we're left 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.

Going ahead to step 9:
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: 3241.0625
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 16, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3241.0625
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.

Moving on to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3241.0625
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.

The final result is 3241.0625 with a remainder of 0.0.
