629940 ÷ 1 
Our goal is to divide 629940 by 1.

On to 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
If we subtract 6 from 6, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Going ahead to step 2:
2 divided by 1 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Deduct 2 from 2 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Let's proceed to step 3:
When dividing 9 by 1, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 629.0
The remainder is 0 after subtracting 9 from 9.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Step 4:
If we divide 9 by 1, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 6299.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 5:
If we divide 4 by 1, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 62994.0
If we take 4 away from 4, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Step 6:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 629940.0
If we subtract 0 from 0, we get 0.
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 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 629940.0
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.

Going ahead to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 629940.0
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 quotient of the division is 629940.0, and the remainder is 0.0.
