We're dividing 670949 by 15 
We want to figure out the number of times 670949 can be divided by 15.

Moving 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 take 0 away from 6, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 15

Moving on to step 2:
15 goes into 67 4 times with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 60 from 67 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 15

On to step 3:
The number 15 fits into 70 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 60 from 70 leaves us with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 15

Let's proceed to step 4:
15 goes into 109 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 447.0
If we subtract 105 from 109, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 15

Moving on to step 5:
If we divide 44 by 15, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 4472.0
The remainder is 14 after subtracting 30 from 44.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 15

Advancing to step 6:
The number 15 fits into 149 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 44729.0
Deduct 135 from 149 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 15, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 44729.9
Subtract 135 from 140 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.

Let's proceed to step 8:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 44729.93
The remainder is 5 after subtracting 45 from 50.
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 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 44729.933
If we take 45 away from 50, we end up with 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 outcome is 44729.933, with a leftover of 0.0005.
