We're dividing 207851 by 16 
We want to figure out the number of times 207851 can be divided by 16.

Let's proceed to step 1:
16 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 16

Going ahead to step 2:
20 divided by 16 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 16 away from 20, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 16

Step 3:
47 divided by 16 is 2 with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 32 from 47 leaves us with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 16

Let's proceed to step 4:
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: 129.0
If we take 144 away from 158, we end up with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 16

Let's proceed to step 5:
When dividing 145 by 16, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 1299.0
The remainder is 1 after subtracting 144 from 145.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 16

On to step 6:
11 divided by 16 is 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 12990.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
16 can be fit into 110 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 12990.6
If we take 96 away from 110, we end up 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.

Moving on to step 8:
The number 16 fits into 140 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 12990.68
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
16 goes into 120 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 12990.687
Subtracting 112 from 120 leaves us 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.

Advancing to step 10:
16 goes into 80 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 12990.6875
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.

Step 11:
16 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12990.6875
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.

On to step 12:
0 divided by 16 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12990.6875
If we subtract 0 from 0, 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.

The quotient of the division is 12990.6875, and the remainder is 0.0.
