671869 ÷ 15 
We want to figure out the number of times 671869 can be divided by 15.

Going ahead to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 15

Advancing to step 2:
When dividing 67 by 15, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 60 from 67 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 15

On to step 3:
71 divided by 15 is 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 11 after subtracting 60 from 71.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 15

Step 4:
15 goes into 118 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 447.0
The remainder is 13 after subtracting 105 from 118.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 15

Let's proceed to step 5:
136 divided by 15 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 4479.0
Deduct 135 from 136 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 15

Going ahead to step 6:
When dividing 19 by 15, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 44791.0
The remainder is 4 after subtracting 15 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 15 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 44791.2
Subtracting 30 from 40 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 44791.26
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 44791.266
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 44791.266 with a remaining 0.001.
