We're dividing 543103 by 15 
Our goal is to divide 543103 by 15.

Let's proceed to step 1:
If we divide 5 by 15, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

Moving on to step 2:
15 goes into 54 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 45 away from 54, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 15

Going ahead to step 3:
93 divided by 15 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 3 after subtracting 90 from 93.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 15

Moving on to step 4:
15 goes into 31 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 362.0
The remainder is 1 after subtracting 30 from 31.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 15

On to step 5:
15 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3620.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 15

On to step 6:
15 can be fit into 103 6 times, resulting in a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 36206.0
If we subtract 90 from 103, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 15, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 36206.8
Deduct 120 from 130 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.

Moving on to step 8:
15 goes into 100 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 36206.86
Subtracting 90 from 100 leaves us 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.

Going ahead to step 9:
15 goes into 100 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 36206.866
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.

The quotient of the division is 36206.866, and the remainder is 0.001.
