143780 ÷ 9 
We're looking to find how many times 9 goes into 143780.

Going ahead to step 1:
9 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 9

On to step 2:
The number 9 fits into 14 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 9 from 14 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 9

Let's proceed to step 3:
9 goes into 53 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 45 from 53 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 9

Going ahead to step 4:
9 goes into 87 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
The remainder is 6 after subtracting 81 from 87.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 9

Advancing to step 5:
68 divided by 9 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1597.0
Subtract 63 from 68 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 9

On to step 6:
50 divided by 9 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15975.0
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 9, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 15975.5
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
9 can be fit into 50 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15975.55
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 15975.55 with a remainder of 0.005.
