We're dividing 660998 by 16 
We're looking to find how many times 16 goes into 660998.

Advancing to step 1:
16 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 16

Let's proceed to step 2:
If we divide 66 by 16, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 64 away from 66, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 16

On to step 3:
The number 16 fits into 20 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 16 from 20 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 16

Moving on to step 4:
49 divided by 16 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 413.0
Deduct 48 from 49 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 16

Going ahead to step 5:
The number 16 fits into 19 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 4131.0
If we take 16 away from 19, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 16

Let's proceed to step 6:
When dividing 38 by 16, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 41312.0
Subtracting 32 from 38 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.

Advancing to step 7:
If we divide 60 by 16, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 41312.3
If we take 48 away from 60, we end up 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.

On to step 8:
When dividing 120 by 16, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 41312.37
Subtracting 112 from 120 leaves us 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.

Moving on to step 9:
When dividing 80 by 16, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 41312.375
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.
Put 0 as the next digit of the answer. 
Result so far: 41312.375
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.

Going ahead to step 11:
When dividing 0 by 16, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41312.375
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.

The final result is 41312.375 with a remainder of 0.0.
