We're dividing 68730857 by 860 
Let's see how many times 860 fits into 68730857.

On to step 1:
The number 860 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 860

Moving on to step 2:
68 divided by 860 is 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 860

On to step 3:
If we divide 687 by 860, we get 0 and a remainder of 687.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 687, we get 687.
Include the next digit (3) from the dividend after 687, then repeat: 6873 / 860

Moving on to step 4:
6873 divided by 860 is 7 with a remainder of 853.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6020 from 6873 leaves us with 853.
Bring next digit (0) of the dividend behind the 853 and repeat the process: 8530 / 860

Advancing to step 5:
860 goes into 8530 9 times with a remainder of 790.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we take 7740 away from 8530, we end up with 790.
Fetch the next digit (8) from the dividend, attach it to 790 and continue: 7908 / 860

On to step 6:
860 goes into 7908 9 times with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 799.0
If we take 7740 away from 7908, we end up with 168.
Include the next digit (5) from the dividend after 168, then repeat: 1685 / 860

On to step 7:
The number 860 fits into 1685 1 times, leaving a remainder of 825.
The next digit of our result is 1. 
Result so far: 7991.0
Subtracting 860 from 1685 leaves us with 825.
Bring next digit (7) of the dividend behind the 825 and repeat the process: 8257 / 860

Let's proceed to step 8:
860 goes into 8257 9 times with a remainder of 517.
Record the quotient 9 as the next digit in the result. 
Result so far: 79919.0
Subtract 7740 from 8257 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Let's proceed to step 9:
860 can be fit into 5170 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 79919.6
Subtracting 5160 from 5170 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.

Step 10:
When dividing 100 by 860, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 79919.6
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
860 can be fit into 1000 1 times, resulting in a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 79919.601
Subtracting 860 from 1000 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
If we divide 1400 by 860, we get 1 and a remainder of 540.
Put 1 as the next digit of the answer. 
Result so far: 79919.6011
Deduct 860 from 1400 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

After the division, we end up with 79919.6011 and a remainder of 0.0054.
