We're dividing 709399 by 1 
We want to figure out the number of times 709399 can be divided by 1.

Step 1:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 0 after subtracting 7 from 7.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Step 2:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Subtract 0 from 0 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Moving on to step 3:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 709.0
If we subtract 9 from 9, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 7093.0
Subtract 3 from 3 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Going ahead to step 5:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 70939.0
Subtracting 9 from 9 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Advancing to step 6:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 709399.0
Subtracting 9 from 9 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 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 709399.0
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.

Going ahead to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 709399.0
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.

The final outcome is 709399.0, with a leftover of 0.0.
