104378 divided by 15 
Our goal is to divide 104378 by 15.

Going ahead to step 1:
When dividing 1 by 15, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 15

Advancing to step 2:
15 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 15

Moving on to step 3:
When dividing 104 by 15, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 90 from 104, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 15

Going ahead to step 4:
If we divide 143 by 15, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we take 135 away from 143, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 15

Advancing to step 5:
When dividing 87 by 15, we get 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 695.0
Subtracting 75 from 87 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 15

Let's proceed to step 6:
If we divide 128 by 15, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 6958.0
Subtract 120 from 128 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 15 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6958.5
If we subtract 75 from 80, 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.

On to step 8:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 6958.53
If we subtract 45 from 50, 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.

Let's proceed to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 6958.533
If we take 45 away from 50, we end up 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.

The final outcome is 6958.533, with a leftover of 0.0005.
