If you want to divide 70000 by 6, it helps to break down the 70000 into parts that you can divide by 6 using mental math alone. It’s easy to verify that 70000 = 60000 + 6000 + 3600 + 360 + 36 + 4. And it’s easy to compute that (60000 + 6000 + 3600 + 360 + 36)/6 = 10000 + 1000 + 600 + 60 + 6.

So 70000/6 = 11666 with a remainder of 4 that couldn’t be divided by 6.

Long division is the technique we use to break the number apart for easier division.

The first step of writing out long division breaks out 60000, shows us we still have 10000 to go, and puts a 1 up as the confirmed first digit of the answer:

1
____
6 | 70000
6
__
10000

I can explain more, but you’d be better served, as another commenter said, watching a video or another form of learning this than a reddit comment.
