353863 ÷ 82 
The aim is to understand the frequency of 82 in 353863.

On to step 1:
If we divide 3 by 82, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 82

On to step 2:
82 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 82

Step 3:
When dividing 353 by 82, we get 4 with a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 328 from 353 and we're left with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 82

Moving on to step 4:
82 goes into 258 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 246 from 258 leaves us with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 82

Step 5:
82 goes into 126 1 times with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 431.0
Subtracting 82 from 126 leaves us with 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 82

Let's proceed to step 6:
When dividing 443 by 82, we get 5 with a remainder of 33.
The next digit of our result is 5. 
Result so far: 4315.0
Subtract 410 from 443 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
82 goes into 330 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4315.4
If we take 328 away from 330, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 82 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4315.4
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
200 divided by 82 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 4315.402
If we subtract 164 from 200, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
82 goes into 360 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4315.4024
Subtract 328 from 360 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
When dividing 320 by 82, we get 3 with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 4315.40243
Deduct 246 from 320 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
740 divided by 82 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 4315.402439
If we take 738 away from 740, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
20 divided by 82 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4315.402439
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
200 divided by 82 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 4315.40243902
Deduct 164 from 200 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 4315.40243902, with a leftover of 3.6e-08.
