Let's divide 459123 by 7
We want to divide 459123 by 7.

Going ahead to step 1:
7 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 7

Going ahead to step 2:
If we divide 45 by 7, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 42 from 45 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 7

Moving on to step 3:
7 goes into 39 5 times with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtracting 35 from 39 leaves us with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 7

Let's proceed to step 4:
41 divided by 7 is 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 655.0
Deduct 35 from 41 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 7

Step 5:
7 goes into 62 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 6558.0
Deduct 56 from 62 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 7

Step 6:
63 divided by 7 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 65589.0
Subtracting 63 from 63 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.

Moving on to step 7:
The number 7 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 65589.0
If we subtract 0 from 0, we get 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:
7 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 65589.0
If we subtract 0 from 0, we get 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 65589.0, and the remainder is 0.0.
