343401 divided by 15 
We want to divide 343401 by 15.

Going ahead to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 15

Let's proceed to step 2:
34 divided by 15 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 30 from 34 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 15

Advancing to step 3:
15 can be fit into 43 2 times, resulting in a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 13 after subtracting 30 from 43.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 15

Advancing to step 4:
When dividing 134 by 15, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 228.0
Subtract 120 from 134 to get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 15

On to step 5:
The number 15 fits into 140 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 2289.0
If we subtract 135 from 140, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 15

Let's proceed to step 6:
15 goes into 51 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 22893.0
Subtract 45 from 51 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
15 can be fit into 60 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 22893.4
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22893.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22893.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 22893.4 with a remainder of 0.0.
