We look at the division of 169789 by 80 
Let's see how many times 80 fits into 169789.

Step 1:
80 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 80

Let's proceed to step 2:
16 divided by 80 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 80

On to step 3:
If we divide 169 by 80, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 160 from 169 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 80

On to step 4:
80 can be fit into 97 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 80 from 97 to get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 80

Let's proceed to step 5:
80 goes into 178 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 212.0
Deduct 160 from 178 and we're left with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 80

Moving on to step 6:
80 goes into 189 2 times with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2122.0
Subtract 160 from 189 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
When dividing 290 by 80, we get 3 with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 2122.3
The remainder is 50 after subtracting 240 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 2122.36
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 2122.362
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2122.3625
Subtract 400 from 400 to 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.

Going ahead to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2122.3625
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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2122.3625
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.

The final result is 2122.3625 with a remainder of 0.0.
