We look at the division of 542786 by 15 
Let's see how many times 15 fits into 542786.

Let's proceed to step 1:
5 divided by 15 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

On to step 2:
If we divide 54 by 15, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 3.0
If we take 45 away from 54, we end up with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 15

Step 3:
The number 15 fits into 92 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 2 after subtracting 90 from 92.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 15

Let's proceed to step 4:
15 can be fit into 27 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 361.0
If we take 15 away from 27, we end up with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 15

Advancing to step 5:
15 goes into 128 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 3618.0
If we subtract 120 from 128, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 15

Advancing to step 6:
When dividing 86 by 15, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 36185.0
Deduct 75 from 86 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
15 goes into 110 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 36185.7
The remainder is 5 after subtracting 105 from 110.
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:
If we divide 50 by 15, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 36185.73
Subtract 45 from 50 to 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.

Advancing to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 36185.733
Subtracting 45 from 50 leaves us 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 outcome is 36185.733, with a leftover of 0.0005.
