We're dividing 860680 by 70 
Let's see how many times 70 fits into 860680.

Advancing to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 70

Advancing to step 2:
70 can be fit into 86 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 16 after subtracting 70 from 86.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 70

Advancing to step 3:
If we divide 160 by 70, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 140 from 160 to get 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 70

Step 4:
If we divide 206 by 70, we get 2 and a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtract 140 from 206 to get 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 70

Going ahead to step 5:
When dividing 668 by 70, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 1229.0
Subtracting 630 from 668 leaves us with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 70

On to step 6:
70 can be fit into 380 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 12295.0
The remainder is 30 after subtracting 350 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 12295.4
If we take 280 away from 300, we end up 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.

Let's proceed to step 8:
If we divide 200 by 70, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 12295.42
Subtract 140 from 200 to get 60.
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 9:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 12295.428
Deduct 560 from 600 and we're left 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.

Going ahead to step 10:
When dividing 400 by 70, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12295.4285
Subtracting 350 from 400 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
70 goes into 500 7 times with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 12295.42857
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.

On to step 12:
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: 12295.428571
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 12295.4285714
Deduct 280 from 300 and we're left 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.

Advancing to step 14:
When dividing 200 by 70, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 12295.42857142
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 12295.42857142, with a leftover of 6e-08.
