We look at the division of 127990 by 10 
Let's see how many times 10 fits into 127990.

On to step 1:
When dividing 1 by 10, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 10

Moving on to step 2:
If we divide 12 by 10, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 10 from 12 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 10

Advancing to step 3:
10 can be fit into 27 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 20 away from 27, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 10

Going ahead to step 4:
If we divide 79 by 10, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we take 70 away from 79, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 10

Advancing to step 5:
99 divided by 10 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 1279.0
The remainder is 9 after subtracting 90 from 99.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 10

On to step 6:
10 goes into 90 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 12799.0
If we take 90 away from 90, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
If we divide 0 by 10, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12799.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12799.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 12799.0 and a remainder of 0.0.
