351992 ÷ 15 
Our goal is to divide 351992 by 15.

Moving on to step 1:
3 divided by 15 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 15

On to step 2:
When dividing 35 by 15, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 30 from 35 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 15

Moving on to step 3:
15 goes into 51 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 45 from 51 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 15

Let's proceed to step 4:
15 can be fit into 69 4 times, resulting in a remainder of 9.
The next digit of our result is 4. 
Result so far: 234.0
The remainder is 9 after subtracting 60 from 69.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 15

On to step 5:
When dividing 99 by 15, we get 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 2346.0
Subtracting 90 from 99 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 15

Going ahead to step 6:
92 divided by 15 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 23466.0
If we subtract 90 from 92, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 15 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 23466.1
If we subtract 15 from 20, 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.

Advancing to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 23466.13
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.

On to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 23466.133
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.

After the division, we end up with 23466.133 and a remainder of 0.0005.
