635509 ÷ 16 
Let's see how many times 16 fits into 635509.

Advancing 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.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 16

Going ahead to step 2:
16 goes into 63 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 48 from 63 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 16

Moving on to step 3:
155 divided by 16 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we take 144 away from 155, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 16

Moving on to step 4:
16 can be fit into 115 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 397.0
Subtracting 112 from 115 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 16

On to step 5:
30 divided by 16 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 3971.0
The remainder is 14 after subtracting 16 from 30.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 16

Let's proceed to step 6:
16 goes into 149 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 39719.0
Deduct 144 from 149 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
16 goes into 50 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 39719.3
Deduct 48 from 50 and we're left 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.

Advancing to step 8:
If we divide 20 by 16, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 39719.31
Subtract 16 from 20 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.

Let's proceed to step 9:
When dividing 40 by 16, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 39719.312
The remainder is 8 after subtracting 32 from 40.
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.
Record the quotient 5 as the next digit in the result. 
Result so far: 39719.3125
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 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39719.3125
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.

Moving on to step 12:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39719.3125
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.

In conclusion, the division gives 39719.3125 with a balance of 0.0.
