Let's divide 165131 by 80
We want to figure out the number of times 165131 can be divided by 80.

Moving on to step 1:
80 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 80

Moving on to step 2:
When dividing 16 by 80, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 80

Moving on to step 3:
165 divided by 80 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 160 from 165 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 80

Going ahead to step 4:
51 divided by 80 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 80

Going ahead to step 5:
513 divided by 80 is 6 with a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 206.0
If we subtract 480 from 513, we get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 80

Moving on to step 6:
If we divide 331 by 80, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 2064.0
Subtract 320 from 331 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
110 divided by 80 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 2064.1
If we take 80 away from 110, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 80 is 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 2064.13
Subtract 240 from 300 to get 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:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 2064.137
Deduct 560 from 600 and we're left 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.

Going ahead to step 10:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2064.1375
If we take 400 away from 400, 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.

Advancing to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2064.1375
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.

Going ahead to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2064.1375
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.

The final outcome is 2064.1375, with a leftover of 0.0.
