We look at the division of 135902 by 9 
Our goal is to divide 135902 by 9.

Advancing to step 1:
1 divided by 9 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 9

Going ahead to step 2:
If we divide 13 by 9, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 9 from 13.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 9

Let's proceed to step 3:
When dividing 45 by 9, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 0 after subtracting 45 from 45.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 9

On to step 4:
If we divide 9 by 9, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 151.0
Deduct 9 from 9 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 9

Moving on to step 5:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1510.0
Subtract 0 from 0 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 9

Step 6:
2 divided by 9 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 15100.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 9, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 15100.2
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
When dividing 20 by 9, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 15100.22
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 15100.22 and a remainder of 0.002.
