Let's divide 428548 by 1
Our goal is to divide 428548 by 1.

Step 1:
If we divide 4 by 1, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Step 2:
When dividing 2 by 1, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 0 after subtracting 2 from 2.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Moving on to step 3:
8 divided by 1 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 428.0
Deduct 8 from 8 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Moving on to step 4:
When dividing 5 by 1, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4285.0
Subtracting 5 from 5 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Moving on to step 5:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 42854.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

On to step 6:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 428548.0
Deduct 8 from 8 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: 428548.0
Subtract 0 from 0 to 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.

Going ahead to step 8:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 428548.0
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.

After the division, we end up with 428548.0 and a remainder of 0.0.
