We divide 848489 by 1
Our goal is to divide 848489 by 1.

Advancing to step 1:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Moving on to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Advancing to step 3:
If we divide 8 by 1, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 848.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 4:
4 divided by 1 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 8484.0
If we subtract 4 from 4, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Step 5:
8 divided by 1 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 84848.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Going ahead to step 6:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 848489.0
If we take 9 away from 9, 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.

Let's proceed to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 848489.0
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.

On to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 848489.0
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.

The final outcome is 848489.0, with a leftover of 0.0.
