We look at the division of 234215 by 81 
Our goal is to divide 234215 by 81.

Going ahead to step 1:
81 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 81

Step 2:
The number 81 fits into 23 0 times, leaving a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 81

Going ahead to step 3:
81 can be fit into 234 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 162 from 234 to get 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 81

On to step 4:
722 divided by 81 is 8 with a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 648 from 722, we get 74.
Append the next digit (1) from the dividend to 74 and continue with: 741 / 81

Moving on to step 5:
81 goes into 741 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 289.0
If we take 729 away from 741, we end up with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 81

On to step 6:
81 can be fit into 125 1 times, resulting in a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 2891.0
Deduct 81 from 125 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
81 goes into 440 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2891.5
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
If we divide 350 by 81, we get 4 and a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 2891.54
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
260 divided by 81 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2891.543
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
The number 81 fits into 170 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2891.5432
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 81, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 2891.5432
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
81 can be fit into 800 9 times, resulting in a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 2891.543209
Deduct 729 from 800 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 13:
81 goes into 710 8 times with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 2891.5432098
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
81 can be fit into 620 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 2891.54320987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 2891.54320987, with a leftover of 5.3e-08.
