921591 ÷ 82 
The aim is to understand the frequency of 82 in 921591.

On to step 1:
9 divided by 82 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 82

Moving on to step 2:
If we divide 92 by 82, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 82 from 92 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 82

Step 3:
When dividing 101 by 82, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 82 away from 101, we end up with 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 82

Let's proceed to step 4:
82 can be fit into 195 2 times, resulting in a remainder of 31.
The next digit of our result is 2. 
Result so far: 112.0
If we subtract 164 from 195, we get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 82

Advancing to step 5:
82 can be fit into 319 3 times, resulting in a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 1123.0
If we take 246 away from 319, we end up with 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 82

Going ahead to step 6:
The number 82 fits into 731 8 times, leaving a remainder of 75.
The number 8 becomes the next digit in our result. 
Result so far: 11238.0
If we take 656 away from 731, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
82 can be fit into 750 9 times, resulting in a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 11238.9
Deduct 738 from 750 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.

Advancing to step 8:
The number 82 fits into 120 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 11238.91
The remainder is 38 after subtracting 82 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
When dividing 380 by 82, we get 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 11238.914
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.

Advancing to step 10:
The number 82 fits into 520 6 times, leaving a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 11238.9146
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.

Advancing to step 11:
82 goes into 280 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 11238.91463
If we take 246 away from 280, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 12:
The number 82 fits into 340 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 11238.914634
If we take 328 away from 340, we end up 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.

Moving on to step 13:
120 divided by 82 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 11238.9146341
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.

Step 14:
The number 82 fits into 380 4 times, leaving a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 11238.91463414
If we take 328 away from 380, 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.

Our division results in 11238.91463414 with a remaining 5.2e-08.
