134840 divided by 90 
Our goal is to divide 134840 by 90.

Moving on to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 90

Let's proceed to step 2:
The number 90 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 90

Step 3:
90 can be fit into 134 1 times, resulting in a remainder of 44.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 44 after subtracting 90 from 134.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 90

Advancing to step 4:
90 can be fit into 448 4 times, resulting in a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 88 after subtracting 360 from 448.
Take the next digit (4) from the dividend and append it to 88, then repeat: 884 / 90

Going ahead to step 5:
If we divide 884 by 90, we get 9 and a remainder of 74.
The next digit of our result is 9. 
Result so far: 149.0
Subtracting 810 from 884 leaves us with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 90

On to step 6:
90 goes into 740 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 1498.0
If we subtract 720 from 740, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
When dividing 200 by 90, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 1498.2
Deduct 180 from 200 and we're left 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.

On to step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1498.22
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 1498.22 with a remainder of 0.02.
