542315 divided by 20 
We want to figure out the number of times 542315 can be divided by 20.

Moving on to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 20

Let's proceed to step 2:
20 can be fit into 54 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 54 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 20

Let's proceed to step 3:
142 divided by 20 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 140 from 142 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 20

Let's proceed to step 4:
The number 20 fits into 23 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
The remainder is 3 after subtracting 20 from 23.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

Let's proceed to step 5:
When dividing 31 by 20, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2711.0
If we take 20 away from 31, we end up with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Going ahead to step 6:
20 can be fit into 115 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 27115.0
If we subtract 100 from 115, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 27115.7
Subtracting 140 from 150 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.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 27115.75
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27115.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 27115.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 27115.75, with a leftover of 0.0.
