We divide 389109 by 1
Let's see how many times 1 fits into 389109.

Moving on to step 1:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

On to step 2:
When dividing 8 by 1, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Let's proceed to step 3:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 389.0
The remainder is 0 after subtracting 9 from 9.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Moving on to step 4:
1 goes into 1 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 3891.0
If we subtract 1 from 1, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Going ahead to step 5:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 38910.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Moving on to step 6:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 389109.0
If we subtract 9 from 9, 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.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 389109.0
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.

Moving on to step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 389109.0
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.

The final outcome is 389109.0, with a leftover of 0.0.
