131870 divided by 81 
We want to divide 131870 by 81.

Advancing to step 1:
81 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
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 81

Moving on to step 2:
If we divide 13 by 81, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 81

Moving on to step 3:
When dividing 131 by 81, we get 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 81 from 131 to get 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 81

Let's proceed to step 4:
508 divided by 81 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 486 from 508 leaves us with 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 81

Step 5:
227 divided by 81 is 2 with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 162.0
The remainder is 65 after subtracting 162 from 227.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 81

Advancing to step 6:
650 divided by 81 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 1628.0
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 81, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1628.0
If we subtract 0 from 20, we get 20.
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 8:
200 divided by 81 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 1628.02
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 9:
If we divide 380 by 81, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 1628.024
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 81, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 1628.0246
Deduct 486 from 560 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 11:
The number 81 fits into 740 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1628.02469
The remainder is 11 after subtracting 729 from 740.
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 12:
When dividing 110 by 81, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1628.024691
Subtract 81 from 110 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.

On to step 13:
290 divided by 81 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 1628.0246913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 14:
When dividing 470 by 81, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 1628.02469135
Deduct 405 from 470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 1628.02469135 and a remainder of 6.5e-08.
