We're dividing 674460 by 16 
We're looking to find how many times 16 goes into 674460.

On to step 1:
16 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 16

On to step 2:
16 can be fit into 67 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 64 away from 67, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 16

Going ahead to step 3:
16 goes into 34 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 32 from 34 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 16

On to step 4:
When dividing 24 by 16, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 421.0
Subtract 16 from 24 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 16

Going ahead to step 5:
The number 16 fits into 86 5 times, leaving a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 4215.0
Deduct 80 from 86 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 16

Step 6:
If we divide 60 by 16, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 42153.0
Subtracting 48 from 60 leaves us 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.

Moving on to step 7:
The number 16 fits into 120 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 42153.7
The remainder is 8 after subtracting 112 from 120.
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 8:
16 goes into 80 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 42153.75
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
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: 42153.75
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.

On to step 10:
16 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 42153.75
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 42153.75 with a remainder of 0.0.
