We divide 81886 by 80
Let's see how many times 80 fits into 81886.

Step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 80

Let's proceed to step 2:
If we divide 81 by 80, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 80 from 81.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 80

On to step 3:
The number 80 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 80

Advancing to step 4:
When dividing 188 by 80, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtracting 160 from 188 leaves us with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 80

Moving on to step 5:
If we divide 286 by 80, we get 3 and a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 1023.0
Deduct 240 from 286 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 6:
80 goes into 460 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 1023.5
If we subtract 400 from 460, we 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.

Moving on to step 7:
When dividing 600 by 80, we get 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 1023.57
If we take 560 away from 600, we end up 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.

Advancing to step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1023.575
The remainder is 0 after subtracting 400 from 400.
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 9:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1023.575
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.

Advancing to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1023.575
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.

In conclusion, the division gives 1023.575 with a balance of 0.0.
