We're dividing 347854 by 15 
We want to figure out the number of times 347854 can be divided by 15.

Step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 15

On to step 2:
The number 15 fits into 34 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 34, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 15

Let's proceed to step 3:
15 can be fit into 47 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 45 from 47 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 15

On to step 4:
15 goes into 28 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 231.0
Deduct 15 from 28 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Let's proceed to step 5:
15 goes into 135 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 2319.0
Subtracting 135 from 135 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 15

On to step 6:
When dividing 4 by 15, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 23190.0
If we subtract 0 from 4, we get 4.
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:
If we divide 40 by 15, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 23190.2
Subtract 30 from 40 to get 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 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 23190.26
If we take 90 away from 100, we end up 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.

Advancing to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 23190.266
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 23190.266, and the remainder is 0.001.
