We look at the division of 353086 by 81 
Let's see how many times 81 fits into 353086.

Advancing to step 1:
3 divided by 81 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 81

Step 2:
The number 81 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 81

On to step 3:
81 can be fit into 353 4 times, resulting in a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 324 from 353 and we're left with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 81

On to step 4:
When dividing 290 by 81, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 47 after subtracting 243 from 290.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 81

On to step 5:
When dividing 478 by 81, we get 5 with a remainder of 73.
Write down 5 as next digit of the result. 
Result so far: 435.0
The remainder is 73 after subtracting 405 from 478.
Take the next digit (6) from the dividend and append it to 73, then repeat: 736 / 81

Moving on to step 6:
The number 81 fits into 736 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 4359.0
Subtract 729 from 736 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 81, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 4359.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
If we divide 700 by 81, we get 8 and a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 4359.08
If we take 648 away from 700, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
81 can be fit into 520 6 times, resulting in a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 4359.086
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
340 divided by 81 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 4359.0864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 81 is 1 with a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 4359.08641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
The number 81 fits into 790 9 times, leaving a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 4359.086419
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 13:
610 divided by 81 is 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 4359.0864197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 14:
81 can be fit into 430 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4359.08641975
Subtracting 405 from 430 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 4359.08641975 with a balance of 2.5e-08.
