We look at the division of 543274 by 15 
Our goal is to divide 543274 by 15.

Moving on to step 1:
15 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 15

Advancing to step 2:
The number 15 fits into 54 3 times, leaving a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 9 after subtracting 45 from 54.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 15

Going ahead to step 3:
15 goes into 93 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 90 from 93 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 15

Step 4:
32 divided by 15 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 362.0
The remainder is 2 after subtracting 30 from 32.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 15

Step 5:
15 can be fit into 27 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 3621.0
Subtracting 15 from 27 leaves us with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 15

On to step 6:
15 can be fit into 124 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 36218.0
The remainder is 4 after subtracting 120 from 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 15, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 36218.2
Subtract 30 from 40 to 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.

Advancing to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 36218.26
If we take 90 away from 100, we end up 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 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 36218.266
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 outcome is 36218.266, with a leftover of 0.001.
