We're dividing 667920 by 1 
We're looking to find how many times 1 goes into 667920.

Let's proceed to step 1:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 6 from 6 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Moving on to step 2:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtract 6 from 6 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Step 3:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 667.0
Subtracting 7 from 7 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Let's proceed to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 6679.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Advancing to step 5:
1 can be fit into 2 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 66792.0
Subtract 2 from 2 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Step 6:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 667920.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 667920.0
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.

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 667920.0
If we take 0 away from 0, 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.

In conclusion, the division gives 667920.0 with a balance of 0.0.
