We look at the division of 16874 by 1 
We're looking to find how many times 1 goes into 16874.

Advancing to step 1:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 1 from 1 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

On to step 2:
When dividing 6 by 1, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Step 3:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 168.0
If we subtract 8 from 8, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 4:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 1687.0
Deduct 7 from 7 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 5:
4 divided by 1 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 16874.0
The remainder is 0 after subtracting 4 from 4.
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 6:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16874.0
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.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16874.0
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.

The quotient of the division is 16874.0, and the remainder is 0.0.
