We look at the division of 691978 by 16 
We want to figure out the number of times 691978 can be divided by 16.

Going ahead 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
Deduct 0 from 6 and we're left with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 16

Going ahead to step 2:
69 divided by 16 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 64 from 69 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 16

Let's proceed to step 3:
The number 16 fits into 51 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 48 from 51 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 16

On to step 4:
When dividing 39 by 16, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 432.0
Subtract 32 from 39 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 16

Step 5:
16 can be fit into 77 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 4324.0
Deduct 64 from 77 and we're left with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 16

On to step 6:
If we divide 138 by 16, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 43248.0
The remainder is 10 after subtracting 128 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
16 goes into 100 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 43248.6
Subtracting 96 from 100 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 8:
16 can be fit into 40 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 43248.62
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.

On to step 9:
16 can be fit into 80 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 43248.625
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:
If we divide 0 by 16, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43248.625
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.

Let's proceed to step 11:
0 divided by 16 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43248.625
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 43248.625 and a remainder of 0.0.
