673040 ÷ 15 
We're looking to find how many times 15 goes into 673040.

On to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 15

Let's proceed to step 2:
15 can be fit into 67 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 7 after subtracting 60 from 67.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 15

On to step 3:
If we divide 73 by 15, we get 4 and a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 60 from 73 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 15

Advancing to step 4:
15 goes into 130 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 448.0
If we take 120 away from 130, we end up with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 15

Going ahead to step 5:
If we divide 104 by 15, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 4486.0
If we subtract 90 from 104, we get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 15

Moving on to step 6:
The number 15 fits into 140 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 44869.0
If we subtract 135 from 140, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 44869.3
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 44869.33
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 44869.33 with a remainder of 0.005.
