We divide 127838 by 90
We're looking to find how many times 90 goes into 127838.

Advancing to step 1:
1 divided by 90 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 90

Moving on to step 2:
12 divided by 90 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 90

On to step 3:
90 can be fit into 127 1 times, resulting in a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 90 from 127 leaves us with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 90

Going ahead to step 4:
378 divided by 90 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 360 from 378, we get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 90

Moving on to step 5:
90 goes into 183 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we subtract 180 from 183, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 90

Going ahead to step 6:
If we divide 38 by 90, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 1420.0
Subtracting 0 from 38 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
The number 90 fits into 380 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 1420.4
If we take 360 away from 380, 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.

Going ahead to step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 1420.42
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 90, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1420.422
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1420.422 and a remainder of 0.002.
