We're dividing 687450 by 16 
We want to figure out the number of times 687450 can be divided by 16.

Moving 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
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 16

On to step 2:
16 can be fit into 68 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 64 away from 68, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 16

Step 3:
47 divided by 16 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 15 after subtracting 32 from 47.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 16

Advancing to step 4:
16 can be fit into 154 9 times, resulting in a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 429.0
Deduct 144 from 154 and we're left with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 16

On to step 5:
If we divide 105 by 16, we get 6 and a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 4296.0
Subtract 96 from 105 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 16

Let's proceed to step 6:
90 divided by 16 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 42965.0
If we take 80 away from 90, we end up 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.

Step 7:
100 divided by 16 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 42965.6
If we take 96 away from 100, we end up 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.

Advancing to step 8:
The number 16 fits into 40 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 42965.62
Subtract 32 from 40 to 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 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 42965.625
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.

On to step 10:
16 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42965.625
If we subtract 0 from 0, 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.

Going ahead to step 11:
The number 16 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 42965.625
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.

After the division, we end up with 42965.625 and a remainder of 0.0.
