Let's divide 349231 by 81
Our goal is to divide 349231 by 81.

Let's proceed to step 1:
3 divided by 81 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 81

Moving on to step 2:
81 can be fit into 34 0 times, resulting in a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 81

Advancing to step 3:
349 divided by 81 is 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 324 from 349 leaves us with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 81

Moving on to step 4:
252 divided by 81 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 243 from 252 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 81

Let's proceed to step 5:
93 divided by 81 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 431.0
The remainder is 12 after subtracting 81 from 93.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 81

Advancing to step 6:
81 can be fit into 121 1 times, resulting in a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 4311.0
If we take 81 away from 121, 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.

Step 7:
When dividing 400 by 81, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 4311.4
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 8:
The number 81 fits into 760 9 times, leaving a remainder of 31.
The next digit of our result is 9. 
Result so far: 4311.49
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.

Advancing to step 9:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 4311.493
If we subtract 243 from 310, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
81 goes into 670 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 4311.4938
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.

Let's proceed to step 11:
When dividing 220 by 81, we get 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 4311.49382
Deduct 162 from 220 and we're left with 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 12:
If we divide 580 by 81, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 4311.493827
If we take 567 away from 580, we end up with 13.
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 13:
81 goes into 130 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 4311.4938271
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 14:
81 goes into 490 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4311.49382716
Subtract 486 from 490 to 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.

The final result is 4311.49382716 with a remainder of 4e-09.
