634407 divided by 16 
We want to figure out the number of times 634407 can be divided by 16.

On to step 1:
The number 16 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 16

Moving on to step 2:
63 divided by 16 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 15 after subtracting 48 from 63.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 16

Moving on to step 3:
154 divided by 16 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 144 away from 154, we end up with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 16

Step 4:
16 can be fit into 104 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 396.0
If we take 96 away from 104, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 16

Moving on to step 5:
The number 16 fits into 80 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3965.0
If we take 80 away from 80, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 16

Going ahead to step 6:
The number 16 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 39650.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
16 can be fit into 70 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 39650.4
Subtracting 64 from 70 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 16 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 39650.43
Subtracting 48 from 60 leaves us with 12.
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.
Record the quotient 7 as the next digit in the result. 
Result so far: 39650.437
If we take 112 away from 120, 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.

Step 10:
The number 16 fits into 80 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 39650.4375
Subtract 80 from 80 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.

Let's proceed to step 11:
16 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39650.4375
Deduct 0 from 0 and we're left 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:
The number 16 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39650.4375
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.

The quotient of the division is 39650.4375, and the remainder is 0.0.
