66107002 divided by 15 
We want to divide 66107002 by 15.

On to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 15

Step 2:
15 goes into 66 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 60 from 66 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 15

Let's proceed to step 3:
15 can be fit into 61 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtract 60 from 61 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 15

Advancing to step 4:
15 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 440.0
Subtract 0 from 10 to get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 15

Step 5:
15 goes into 107 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 4407.0
Subtract 105 from 107 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 15

Advancing to step 6:
If we divide 20 by 15, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 44071.0
The remainder is 5 after subtracting 15 from 20.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 15

Step 7:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 440713.0
Deduct 45 from 50 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 15

Advancing to step 8:
When dividing 52 by 15, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4407133.0
Subtract 45 from 52 to 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:
70 divided by 15 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4407133.4
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.

Moving on to step 10:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4407133.46
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 11:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4407133.466
Deduct 90 from 100 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.

In conclusion, the division gives 4407133.466 with a balance of 0.001.
