135957 divided by 90 
Our goal is to divide 135957 by 90.

Moving on to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 90

On to step 2:
13 divided by 90 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 90

Step 3:
When dividing 135 by 90, we get 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 90 from 135, we get 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 90

Step 4:
When dividing 459 by 90, we get 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 450 from 459 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 90

Let's proceed to step 5:
If we divide 95 by 90, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
Subtracting 90 from 95 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 90

Let's proceed to step 6:
90 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 1510.0
Subtracting 0 from 57 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
570 divided by 90 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 1510.6
The remainder is 30 after subtracting 540 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 1510.63
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 90, we get 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 1510.633
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 1510.633 with a remaining 0.003.
