We're dividing 81783 by 80 
We want to figure out the number of times 81783 can be divided by 80.

Step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 80

Let's proceed to step 2:
80 can be fit into 81 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 80 from 81.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 80

Advancing to step 3:
80 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 80

Going ahead to step 4:
When dividing 178 by 80, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtracting 160 from 178 leaves us with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 80

Going ahead to step 5:
183 divided by 80 is 2 with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 1022.0
The remainder is 23 after subtracting 160 from 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 6:
80 can be fit into 230 2 times, resulting in a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 1022.2
The remainder is 70 after subtracting 160 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
When dividing 700 by 80, we get 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 1022.28
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1022.287
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1022.2875
Subtracting 400 from 400 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 10:
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: 1022.2875
Subtract 0 from 0 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.

Let's proceed to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1022.2875
If we take 0 away from 0, we end up 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.

After the division, we end up with 1022.2875 and a remainder of 0.0.
