We look at the division of 839485 by 1 
We want to figure out the number of times 839485 can be divided by 1.

Going ahead to step 1:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Going ahead to step 2:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Advancing to step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 839.0
Subtracting 9 from 9 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Let's proceed to step 4:
1 goes into 4 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 8394.0
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

Advancing to step 5:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 83948.0
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

Let's proceed to step 6:
5 divided by 1 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 839485.0
Subtract 5 from 5 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.

Moving on to step 7:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 839485.0
Subtracting 0 from 0 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.

Step 8:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 839485.0
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.

In conclusion, the division gives 839485.0 with a balance of 0.0.
