We're dividing 76703062 by 15 
We want to divide 76703062 by 15.

Step 1:
If we divide 7 by 15, we get 0 and 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.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 15

Step 2:
When dividing 76 by 15, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 75 from 76, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 15

Step 3:
If we divide 17 by 15, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 15 from 17 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 15

On to step 4:
If we divide 20 by 15, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 511.0
Deduct 15 from 20 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 15

Advancing to step 5:
The number 15 fits into 53 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 5113.0
If we subtract 45 from 53, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 15

Let's proceed to step 6:
80 divided by 15 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 51135.0
Subtract 75 from 80 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 15

Going ahead to step 7:
If we divide 56 by 15, we get 3 and a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 511353.0
Deduct 45 from 56 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 15

On to step 8:
If we divide 112 by 15, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 5113537.0
If we subtract 105 from 112, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
If we divide 70 by 15, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 5113537.4
Subtracting 60 from 70 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.

On to step 10:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 5113537.46
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.

Step 11:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 5113537.466
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.

In conclusion, the division gives 5113537.466 with a balance of 0.001.
