We divide 646285 by 16
We want to figure out the number of times 646285 can be divided by 16.

Going ahead to step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 16

Moving on to step 2:
If we divide 64 by 16, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 64 from 64, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 16

Let's proceed to step 3:
6 divided by 16 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 16

Let's proceed to step 4:
If we divide 62 by 16, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 403.0
The remainder is 14 after subtracting 48 from 62.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 16

Let's proceed to step 5:
When dividing 148 by 16, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 4039.0
If we take 144 away from 148, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 16

Let's proceed to step 6:
45 divided by 16 is 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 40392.0
Subtracting 32 from 45 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
130 divided by 16 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 40392.8
Subtracting 128 from 130 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 16, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 40392.81
Subtracting 16 from 20 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 9:
If we divide 40 by 16, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 40392.812
If we take 32 away from 40, we end up 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 10:
16 goes into 80 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 40392.8125
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.

Advancing to step 11:
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: 40392.8125
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.

Let's proceed to step 12:
16 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 40392.8125
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.

After the division, we end up with 40392.8125 and a remainder of 0.0.
