685720 ÷ 70 
We want to divide 685720 by 70.

Going ahead to step 1:
When dividing 6 by 70, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 70

Step 2:
The number 70 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 70

Step 3:
If we divide 685 by 70, we get 9 and a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 630 from 685 and we're left with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 70

Moving on to step 4:
The number 70 fits into 557 7 times, leaving a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 97.0
The remainder is 67 after subtracting 490 from 557.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 70

Going ahead to step 5:
If we divide 672 by 70, we get 9 and a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 979.0
If we subtract 630 from 672, we get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 70

Going ahead to step 6:
If we divide 420 by 70, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 9796.0
If we subtract 420 from 420, 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:
70 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9796.0
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.

Let's proceed to step 8:
If we divide 0 by 70, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9796.0
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 9796.0 with a balance of 0.0.
