Let's divide 666515 by 1
We want to divide 666515 by 1.

Moving on to step 1:
When dividing 6 by 1, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Step 2:
If we divide 6 by 1, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 66.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

On to step 3:
1 goes into 6 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 666.0
If we take 6 away from 6, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Moving on to step 4:
1 goes into 5 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6665.0
If we subtract 5 from 5, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Let's proceed to step 5:
If we divide 1 by 1, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 66651.0
If we take 1 away from 1, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Moving on to step 6:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 666515.0
Deduct 5 from 5 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.

Advancing to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 666515.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 666515.0
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.

After the division, we end up with 666515.0 and a remainder of 0.0.
