We're dividing 438985 by 1 
We want to figure out the number of times 438985 can be divided by 1.

Advancing to step 1:
4 divided by 1 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 2:
If we divide 3 by 1, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

On to step 3:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 438.0
Subtract 8 from 8 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Moving on to step 4:
When dividing 9 by 1, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 4389.0
Subtract 9 from 9 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

On to step 5:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 43898.0
Subtract 8 from 8 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 438985.0
The remainder is 0 after subtracting 5 from 5.
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 438985.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 438985.0
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.

In conclusion, the division gives 438985.0 with a balance of 0.0.
