We divide 7102780 by 15
We want to figure out the number of times 7102780 can be divided by 15.

Moving on to step 1:
7 divided by 15 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 15

Step 2:
15 can be fit into 71 4 times, resulting in a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 60 from 71, we get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 15

Step 3:
The number 15 fits into 110 7 times, leaving a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 105 away from 110, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 15

Step 4:
If we divide 52 by 15, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 473.0
If we subtract 45 from 52, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 15

Let's proceed to step 5:
When dividing 77 by 15, we get 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 4735.0
If we take 75 away from 77, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 15

Let's proceed to step 6:
28 divided by 15 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 47351.0
Subtract 15 from 28 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 15

On to step 7:
15 can be fit into 130 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 473518.0
Deduct 120 from 130 and we're left 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:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 473518.6
Subtracting 90 from 100 leaves us 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.

Going ahead to step 9:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 473518.66
If we subtract 90 from 100, we 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.

In conclusion, the division gives 473518.66 with a balance of 0.01.
