786644 ÷ 16 
We want to divide 786644 by 16.

Let's proceed to step 1:
16 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 16

Going ahead to step 2:
The number 16 fits into 78 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 64 from 78 and we're left with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 16

Advancing to step 3:
The number 16 fits into 146 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 144 from 146, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 16

Step 4:
The number 16 fits into 26 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 491.0
If we take 16 away from 26, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 16

On to step 5:
If we divide 104 by 16, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 4916.0
Subtracting 96 from 104 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 16

Let's proceed to step 6:
The number 16 fits into 84 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 49165.0
Subtract 80 from 84 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.

Going ahead to step 7:
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: 49165.2
Subtracting 32 from 40 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.

On to step 8:
If we divide 80 by 16, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 49165.25
Subtracting 80 from 80 leaves us 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.

Going ahead to step 9:
16 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49165.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 16, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49165.25
Subtracting 0 from 0 leaves us 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 outcome is 49165.25, with a leftover of 0.0.
