585270 ÷ 70 
Our goal is to divide 585270 by 70.

Step 1:
If we divide 5 by 70, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 70

Moving on to step 2:
58 divided by 70 is 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 70

Moving on to step 3:
70 can be fit into 585 8 times, resulting in a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 560 from 585, we get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 70

On to step 4:
70 can be fit into 252 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Deduct 210 from 252 and we're left with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 70

Advancing to step 5:
If we divide 427 by 70, we get 6 and a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 836.0
If we take 420 away from 427, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 70

Advancing to step 6:
The number 70 fits into 70 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 8361.0
If we subtract 70 from 70, 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.

Advancing to step 7:
If we divide 0 by 70, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8361.0
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.

On to step 8:
0 divided by 70 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8361.0
Subtract 0 from 0 to 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.

After the division, we end up with 8361.0 and a remainder of 0.0.
