143200 divided by 15 
We want to divide 143200 by 15.

Going ahead to step 1:
1 divided by 15 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 15

Advancing to step 2:
14 divided by 15 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 15

Going ahead to step 3:
15 goes into 143 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 135 from 143, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 15

Moving on to step 4:
When dividing 82 by 15, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we take 75 away from 82, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 15

Step 5:
15 can be fit into 70 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 954.0
Subtract 60 from 70 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 15

Advancing to step 6:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 9546.0
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 9546.6
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 9546.66
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 9546.66 with a remainder of 0.01.
