We look at the division of 860980 by 48 
We're looking to find how many times 48 goes into 860980.

Going ahead to step 1:
48 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 48

Moving on to step 2:
When dividing 86 by 48, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 48 from 86 leaves us with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 48

Going ahead to step 3:
48 goes into 380 7 times with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtract 336 from 380 to get 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 48

Moving on to step 4:
449 divided by 48 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtracting 432 from 449 leaves us with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 48

Moving on to step 5:
48 can be fit into 178 3 times, resulting in a remainder of 34.
The next digit of our result is 3. 
Result so far: 1793.0
The remainder is 34 after subtracting 144 from 178.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 48

Moving on to step 6:
48 goes into 340 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 17937.0
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
40 divided by 48 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 17937.0
If we take 0 away from 40, 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.

Going ahead to step 8:
The number 48 fits into 400 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 17937.08
Subtracting 384 from 400 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
48 goes into 160 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 17937.083
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 48 fits into 160 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 17937.0833
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 17937.0833, with a leftover of 0.00016.
