We look at the division of 331429 by 81 
Let's see how many times 81 fits into 331429.

On to step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 81

Let's proceed to step 2:
The number 81 fits into 33 0 times, leaving a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 81

Moving on to step 3:
331 divided by 81 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 324 from 331, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 81

Going ahead to step 4:
When dividing 74 by 81, we get 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 74 to get 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 81

Advancing to step 5:
81 goes into 742 9 times with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
If we subtract 729 from 742, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 81

Advancing to step 6:
If we divide 139 by 81, we get 1 and a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 4091.0
Subtract 81 from 139 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
If we divide 580 by 81, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 4091.7
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
81 goes into 130 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 4091.71
Subtract 81 from 130 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 9:
490 divided by 81 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 4091.716
If we subtract 486 from 490, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
If we divide 40 by 81, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4091.716
If we take 0 away from 40, 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.

Going ahead to step 11:
400 divided by 81 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 4091.71604
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
If we divide 760 by 81, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 4091.716049
Subtract 729 from 760 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
81 goes into 310 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 4091.7160493
If we take 243 away from 310, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 14:
When dividing 670 by 81, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 4091.71604938
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 4091.71604938, and the remainder is 2.2e-08.
