Let's divide 389660 by 1
Let's see how many times 1 fits into 389660.

Moving on to step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Step 2:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 8 from 8, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Let's proceed to step 3:
If we divide 9 by 1, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 389.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Going ahead to step 4:
If we divide 6 by 1, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 3896.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Moving on to step 5:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 38966.0
The remainder is 0 after subtracting 6 from 6.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Let's proceed to step 6:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 389660.0
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.

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: 389660.0
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.

Moving 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: 389660.0
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 389660.0 with a balance of 0.0.
