132631 ÷ 81 
Let's see how many times 81 fits into 132631.

Step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 81

Step 2:
The number 81 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 81

Let's proceed to step 3:
If we divide 132 by 81, we get 1 and a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 81 from 132 to get 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 81

Moving on to step 4:
81 goes into 516 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 486 from 516 leaves us with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 81

Going ahead to step 5:
303 divided by 81 is 3 with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 163.0
Subtracting 243 from 303 leaves us with 60.
Fetch the next digit (1) from the dividend, attach it to 60 and continue: 601 / 81

On to step 6:
81 goes into 601 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 1637.0
Subtracting 567 from 601 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 1637.4
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
When dividing 160 by 81, we get 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 1637.41
If we subtract 81 from 160, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
If we divide 790 by 81, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 1637.419
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
81 goes into 610 7 times with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 1637.4197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 11:
If we divide 430 by 81, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1637.41975
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
If we divide 250 by 81, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1637.419753
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
If we divide 70 by 81, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1637.419753
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
The number 81 fits into 700 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 1637.41975308
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 1637.41975308 with a remainder of 5.2e-08.
