Let's divide 353239 by 81
We want to divide 353239 by 81.

Going ahead 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
If we take 0 away from 3, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 81

Let's proceed to step 2:
35 divided by 81 is 0 with a remainder of 35.
The number 0 becomes the next digit in our 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

Going ahead to step 3:
81 goes into 353 4 times with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 324 from 353, we get 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 81

Moving on to step 4:
If we divide 292 by 81, we get 3 and a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 243 from 292 to get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 81

Advancing to step 5:
If we divide 493 by 81, we get 6 and a remainder of 7.
The next digit of our result is 6. 
Result so far: 436.0
If we subtract 486 from 493, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 81

Step 6:
When dividing 79 by 81, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 4360.0
Deduct 0 from 79 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 7:
81 goes into 790 9 times with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 4360.9
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 8:
610 divided by 81 is 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 4360.97
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 4360.975
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 4360.9753
If we subtract 243 from 250, we 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.

Let's proceed to step 11:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 4360.9753
Subtracting 0 from 70 leaves us 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.

Advancing to step 12:
700 divided by 81 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 4360.975308
Deduct 648 from 700 and we're left 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.

Step 13:
The number 81 fits into 520 6 times, leaving a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 4360.9753086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
81 can be fit into 340 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 4360.97530864
If we subtract 324 from 340, we 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.

The quotient of the division is 4360.97530864, and the remainder is 1.6e-08.
