We're dividing 135646 by 9 
Let's see how many times 9 fits into 135646.

Advancing to step 1:
9 goes into 1 0 times 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.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 9

Advancing to step 2:
The number 9 fits into 13 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 4 after subtracting 9 from 13.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 9

Advancing to step 3:
The number 9 fits into 45 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 45 from 45 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 9

Advancing to step 4:
9 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 9

Going ahead to step 5:
9 goes into 64 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1507.0
Deduct 63 from 64 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 9

Let's proceed to step 6:
9 goes into 16 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 15071.0
If we subtract 9 from 16, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
When dividing 70 by 9, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 15071.7
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
70 divided by 9 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 15071.77
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 15071.77, with a leftover of 0.007.
