Let's divide 389689 by 80
We're looking to find how many times 80 goes into 389689.

Advancing to step 1:
The number 80 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 80

On to step 2:
38 divided by 80 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 80

Advancing to step 3:
The number 80 fits into 389 4 times, leaving a remainder of 69.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 320 from 389 and we're left with 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 80

Step 4:
If we divide 696 by 80, we get 8 and a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtract 640 from 696 to get 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 80

Going ahead to step 5:
80 can be fit into 568 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 487.0
Deduct 560 from 568 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 80

Advancing to step 6:
89 divided by 80 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 4871.0
Subtract 80 from 89 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 80, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 4871.1
Deduct 80 from 90 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
80 goes into 100 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 4871.11
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 4871.11, with a leftover of 0.02.
