657641 divided by 16 
Let's see how many times 16 fits into 657641.

On to step 1:
16 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 16

On to step 2:
16 can be fit into 65 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 1 after subtracting 64 from 65.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 16

Moving on to step 3:
16 goes into 17 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
The remainder is 1 after subtracting 16 from 17.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 16

Moving on to step 4:
16 divided by 16 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 411.0
Subtract 16 from 16 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 16

Let's proceed to step 5:
When dividing 4 by 16, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 4110.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 16

Going ahead to step 6:
16 can be fit into 41 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 41102.0
Subtracting 32 from 41 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
16 can be fit into 90 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 41102.5
Subtracting 80 from 90 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.

Moving on to step 8:
The number 16 fits into 100 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 41102.56
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: 41102.562
If we subtract 32 from 40, we 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.

Going ahead to step 10:
80 divided by 16 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 41102.5625
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.

Let's proceed to step 11:
16 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41102.5625
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.

Step 12:
0 divided by 16 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41102.5625
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.

After the division, we end up with 41102.5625 and a remainder of 0.0.
