664934 ÷ 1 
We're looking to find how many times 1 goes into 664934.

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

On to step 2:
If we divide 6 by 1, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 6 away from 6, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Going ahead to step 3:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 664.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 4:
1 goes into 9 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 6649.0
The remainder is 0 after subtracting 9 from 9.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Let's proceed to step 5:
1 goes into 3 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 66493.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Let's proceed to step 6:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 664934.0
The remainder is 0 after subtracting 4 from 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 664934.0
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:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 664934.0
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.

The final outcome is 664934.0, with a leftover of 0.0.
