We divide 666699 by 15
We want to figure out the number of times 666699 can be divided by 15.

Going ahead to step 1:
6 divided by 15 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 15

Advancing to step 2:
15 goes into 66 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 60 away from 66, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 15

Moving on to step 3:
When dividing 66 by 15, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 60 from 66 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 15

Going ahead to step 4:
When dividing 66 by 15, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 444.0
The remainder is 6 after subtracting 60 from 66.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 15

Let's proceed to step 5:
69 divided by 15 is 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4444.0
The remainder is 9 after subtracting 60 from 69.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 15

Moving on to step 6:
15 can be fit into 99 6 times, resulting in a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 44446.0
Subtract 90 from 99 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 15, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 44446.6
If we take 90 away from 90, we end up 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.

Advancing to step 8:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 44446.6
Deduct 0 from 0 and we're left 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.

Step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 44446.6
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 44446.6 with a balance of 0.0.
