Let's divide 49689 by 80
We want to figure out the number of times 49689 can be divided by 80.

Going ahead to step 1:
80 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 80

Step 2:
80 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 80

Advancing to step 3:
When dividing 496 by 80, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 480 away from 496, we end up with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 80

Advancing to step 4:
If we divide 168 by 80, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 62.0
Deduct 160 from 168 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 80

Let's proceed to step 5:
80 goes into 89 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 621.0
If we take 80 away from 89, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 6:
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: 621.1
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 7:
80 goes into 100 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 621.11
If we take 80 away from 100, we end up 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 result is 621.11 with a remainder of 0.02.
