We divide 164571 by 80
We want to divide 164571 by 80.

Going ahead to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 80

Let's proceed to step 2:
The number 80 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 80

Going ahead to step 3:
When dividing 164 by 80, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 160 from 164, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 80

Advancing to step 4:
80 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 80

Going ahead to step 5:
The number 80 fits into 457 5 times, leaving a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 205.0
The remainder is 57 after subtracting 400 from 457.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 80

Step 6:
80 goes into 571 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 2057.0
Subtracting 560 from 571 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 80 fits into 110 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 2057.1
If we subtract 80 from 110, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 2057.13
Subtracting 240 from 300 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 2057.137
Subtracting 560 from 600 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:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2057.1375
If we subtract 400 from 400, 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.

On to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2057.1375
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.

On to step 12:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2057.1375
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.

The quotient of the division is 2057.1375, and the remainder is 0.0.
