Let's divide 686880 by 70
We want to divide 686880 by 70.

On to step 1:
6 divided by 70 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 70

Moving on to step 2:
68 divided by 70 is 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 70

Moving on to step 3:
70 can be fit into 686 9 times, resulting in a remainder of 56.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 56 after subtracting 630 from 686.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 70

On to step 4:
568 divided by 70 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 560 away from 568, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 70

Let's proceed to step 5:
70 goes into 88 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 981.0
Subtracting 70 from 88 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 70

On to step 6:
When dividing 180 by 70, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 9812.0
The remainder is 40 after subtracting 140 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
When dividing 400 by 70, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 9812.5
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 9812.57
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 9812.571
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9812.5714
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 70, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 9812.57142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 9812.571428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9812.5714285
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 9812.57142857
Subtracting 490 from 500 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 9812.57142857 with a balance of 1e-08.
