We look at the division of 542789 by 1 
Our goal is to divide 542789 by 1.

On to step 1:
1 goes into 5 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 5 from 5 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Step 2:
1 goes into 4 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Let's proceed to step 3:
If we divide 2 by 1, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 542.0
The remainder is 0 after subtracting 2 from 2.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 4:
7 divided by 1 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 5427.0
The remainder is 0 after subtracting 7 from 7.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Let's proceed to step 5:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 54278.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Moving on to step 6:
When dividing 9 by 1, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 542789.0
The remainder is 0 after subtracting 9 from 9.
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 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 542789.0
Deduct 0 from 0 and we're left 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 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 542789.0
If we take 0 away from 0, we end up 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 result is 542789.0 with a remainder of 0.0.
