We divide 842530 by 1
Our goal is to divide 842530 by 1.

Going ahead to step 1:
1 goes into 8 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 8 away from 8, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Let's proceed to 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: 84.0
If we take 4 away from 4, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

On to step 3:
1 goes into 2 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 842.0
The remainder is 0 after subtracting 2 from 2.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Advancing to step 4:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8425.0
Subtracting 5 from 5 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

On to step 5:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 84253.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

On to step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 842530.0
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.

Advancing to step 7:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 842530.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 842530.0
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.

The quotient of the division is 842530.0, and the remainder is 0.0.
