319658 divided by 15 
We want to figure out the number of times 319658 can be divided by 15.

Advancing to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

On to step 2:
15 goes into 31 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 30 from 31 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 15

On to step 3:
15 goes into 19 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 4 after subtracting 15 from 19.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 15

On to step 4:
46 divided by 15 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
Subtract 45 from 46 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 15

Step 5:
When dividing 15 by 15, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 2131.0
Subtract 15 from 15 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 15

Let's proceed to step 6:
The number 15 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 21310.0
If we take 0 away from 8, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
When dividing 80 by 15, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 21310.5
The remainder is 5 after subtracting 75 from 80.
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:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 21310.53
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.

Step 9:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 21310.533
Subtracting 45 from 50 leaves us 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.

Our division results in 21310.533 with a remaining 0.0005.
