We're dividing 252490 by 82 
The aim is to understand the frequency of 82 in 252490.

On to step 1:
If we divide 2 by 82, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 82

Advancing to step 2:
The number 82 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 82

Let's proceed to step 3:
If we divide 252 by 82, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 246 from 252 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 82

Advancing to step 4:
When dividing 64 by 82, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtract 0 from 64 to get 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 82

Advancing to step 5:
If we divide 649 by 82, we get 7 and a remainder of 75.
The next digit of our result is 7. 
Result so far: 307.0
If we subtract 574 from 649, we get 75.
Fetch the next digit (0) from the dividend, attach it to 75 and continue: 750 / 82

Advancing to step 6:
The number 82 fits into 750 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 3079.0
Subtracting 738 from 750 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
82 goes into 120 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 3079.1
Subtract 82 from 120 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
When dividing 380 by 82, we get 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 3079.14
The remainder is 52 after subtracting 328 from 380.
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:
82 goes into 520 6 times with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 3079.146
If we take 492 away from 520, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
If we divide 280 by 82, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 3079.1463
The remainder is 34 after subtracting 246 from 280.
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 11:
If we divide 340 by 82, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 3079.14634
Deduct 328 from 340 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
82 can be fit into 120 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 3079.146341
Deduct 82 from 120 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
If we divide 380 by 82, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 3079.1463414
Subtracting 328 from 380 leaves us 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 14:
If we divide 520 by 82, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 3079.14634146
If we take 492 away from 520, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 3079.14634146, and the remainder is 2.8e-08.
