Let's divide 286509 by 81
Let's see how many times 81 fits into 286509.

Let's proceed to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 81

Step 2:
If we divide 28 by 81, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 81

Advancing to step 3:
If we divide 286 by 81, we get 3 and a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 243 from 286 leaves us with 43.
Bring next digit (5) of the dividend behind the 43 and repeat the process: 435 / 81

Moving on to step 4:
81 can be fit into 435 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 405 from 435 and we're left with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 81

On to step 5:
81 goes into 300 3 times with a remainder of 57.
The next digit of our result is 3. 
Result so far: 353.0
Deduct 243 from 300 and we're left with 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 81

Step 6:
The number 81 fits into 579 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 3537.0
The remainder is 12 after subtracting 567 from 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
The number 81 fits into 120 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 3537.1
The remainder is 39 after subtracting 81 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
81 goes into 390 4 times with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 3537.14
The remainder is 66 after subtracting 324 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
660 divided by 81 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 3537.148
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
If we divide 120 by 81, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 3537.1481
Deduct 81 from 120 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
81 goes into 390 4 times with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 3537.14814
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
The number 81 fits into 660 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3537.148148
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
If we divide 120 by 81, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 3537.1481481
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 14:
If we divide 390 by 81, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 3537.14814814
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 3537.14814814, and the remainder is 6.6e-08.
