We look at the division of 16860039 by 775 
We want to divide 16860039 by 775.

On to step 1:
The number 775 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 775

Advancing to step 2:
When dividing 16 by 775, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 775

Going ahead to step 3:
775 can be fit into 168 0 times, resulting in a remainder of 168.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 168, we get 168.
Bring next digit (6) of the dividend behind the 168 and repeat the process: 1686 / 775

Advancing to step 4:
775 can be fit into 1686 2 times, resulting in a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 136 after subtracting 1550 from 1686.
Include the next digit (0) from the dividend after 136, then repeat: 1360 / 775

On to step 5:
775 goes into 1360 1 times with a remainder of 585.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 585 after subtracting 775 from 1360.
Fetch the next digit (0) from the dividend, attach it to 585 and continue: 5850 / 775

Step 6:
When dividing 5850 by 775, we get 7 with a remainder of 425.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
If we take 5425 away from 5850, we end up with 425.
Take the next digit (3) from the dividend and append it to 425, then repeat: 4253 / 775

Moving on to step 7:
If we divide 4253 by 775, we get 5 and a remainder of 378.
Write down 5 as next digit of the result. 
Result so far: 2175.0
If we take 3875 away from 4253, we end up with 378.
Fetch the next digit (9) from the dividend, attach it to 378 and continue: 3789 / 775

Let's proceed to step 8:
3789 divided by 775 is 4 with a remainder of 689.
The number 4 becomes the next digit in our result. 
Result so far: 21754.0
If we take 3100 away from 3789, we end up with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Let's proceed to step 9:
The number 775 fits into 6890 8 times, leaving a remainder of 690.
Put 8 as the next digit of the answer. 
Result so far: 21754.8
Subtract 6200 from 6890 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 10:
If we divide 6900 by 775, we get 8 and a remainder of 700.
Use 8 as the next digit of our solution. 
Result so far: 21754.88
Subtracting 6200 from 6900 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 21754.88, with a leftover of 0.7.
