70209 ÷ 5 
Our goal is to divide 70209 by 5.

Going ahead to step 1:
When dividing 7 by 5, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 5 from 7 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 5

Advancing to step 2:
The number 5 fits into 20 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 20 from 20 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 5

Advancing to step 3:
2 divided by 5 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 5

Going ahead to step 4:
5 goes into 20 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1404.0
If we take 20 away from 20, we end up with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 5

Let's proceed to step 5:
The number 5 fits into 9 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 14041.0
The remainder is 4 after subtracting 5 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 6:
When dividing 40 by 5, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 14041.8
If we subtract 40 from 40, 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.

On to step 7:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 14041.8
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.

Moving on to step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14041.8
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 14041.8, with a leftover of 0.0.
