349210 divided by 15 
Let's see how many times 15 fits into 349210.

On to step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 15

Going ahead to step 2:
15 can be fit into 34 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 30 away from 34, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 15

On to step 3:
If we divide 49 by 15, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 45 from 49 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 15

Moving on to step 4:
15 goes into 42 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 232.0
Deduct 30 from 42 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 15

Let's proceed to step 5:
121 divided by 15 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 2328.0
Deduct 120 from 121 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 15

Step 6:
15 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 23280.0
If we take 0 away from 10, 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 7:
If we divide 100 by 15, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 23280.6
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.

Step 8:
100 divided by 15 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 23280.66
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 23280.66, with a leftover of 0.01.
