81284102 ÷ 331 
Let's see how many times 331 fits into 81284102.

On to step 1:
331 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 331

Going ahead to step 2:
The number 331 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 331

Going ahead to step 3:
The number 331 fits into 812 2 times, leaving a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 662 from 812 leaves us with 150.
Append the next digit (8) from the dividend to 150 and continue with: 1508 / 331

Advancing to step 4:
The number 331 fits into 1508 4 times, leaving a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 1324 from 1508, we get 184.
Take the next digit (4) from the dividend and append it to 184, then repeat: 1844 / 331

Let's proceed to step 5:
331 goes into 1844 5 times with a remainder of 189.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
If we take 1655 away from 1844, we end up with 189.
Take the next digit (1) from the dividend and append it to 189, then repeat: 1891 / 331

Let's proceed to step 6:
The number 331 fits into 1891 5 times, leaving a remainder of 236.
Write down 5 as next digit of the result. 
Result so far: 2455.0
Subtract 1655 from 1891 to get 236.
Fetch the next digit (0) from the dividend, attach it to 236 and continue: 2360 / 331

Advancing to step 7:
The number 331 fits into 2360 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 24557.0
Subtract 2317 from 2360 to get 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 331

Let's proceed to step 8:
The number 331 fits into 432 1 times, leaving a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 245571.0
The remainder is 101 after subtracting 331 from 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 9:
1010 divided by 331 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 245571.3
Deduct 993 from 1010 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
170 divided by 331 is 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 245571.3
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
When dividing 1700 by 331, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 245571.305
Deduct 1655 from 1700 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
331 goes into 450 1 times with a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 245571.3051
The remainder is 119 after subtracting 331 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 13:
If we divide 1190 by 331, we get 3 and a remainder of 197.
The next digit of our result is 3. 
Result so far: 245571.30513
Subtract 993 from 1190 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 14:
331 goes into 1970 5 times with a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 245571.305135
Subtract 1655 from 1970 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 15:
331 can be fit into 3150 9 times, resulting in a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 245571.3051359
The remainder is 171 after subtracting 2979 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 16:
If we divide 1710 by 331, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 245571.30513595
If we take 1655 away from 1710, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 245571.30513595 with a remainder of 5.5e-08.
