Let's divide 21682958 by 515
The aim is to understand the frequency of 515 in 21682958.

Going ahead to step 1:
2 divided by 515 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 515

Going ahead to step 2:
If we divide 21 by 515, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 515

Going ahead to step 3:
If we divide 216 by 515, we get 0 and a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 216, we end up with 216.
Bring next digit (8) of the dividend behind the 216 and repeat the process: 2168 / 515

Step 4:
When dividing 2168 by 515, we get 4 with a remainder of 108.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 108 after subtracting 2060 from 2168.
Append the next digit (2) from the dividend to 108 and continue with: 1082 / 515

On to step 5:
The number 515 fits into 1082 2 times, leaving a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 1030 from 1082 and we're left with 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 515

Let's proceed to step 6:
529 divided by 515 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
Subtract 515 from 529 to get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 515

Moving on to step 7:
145 divided by 515 is 0 with a remainder of 145.
The number 0 becomes the next digit in our result. 
Result so far: 4210.0
Subtracting 0 from 145 leaves us with 145.
Bring next digit (8) of the dividend behind the 145 and repeat the process: 1458 / 515

Step 8:
1458 divided by 515 is 2 with a remainder of 428.
The next digit of our result is 2. 
Result so far: 42102.0
Deduct 1030 from 1458 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 9:
515 goes into 4280 8 times with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 42102.8
The remainder is 160 after subtracting 4120 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
515 can be fit into 1600 3 times, resulting in a remainder of 55.
The next digit of our result is 3. 
Result so far: 42102.83
Subtract 1545 from 1600 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
515 can be fit into 550 1 times, resulting in a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 42102.831
If we take 515 away from 550, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 515 fits into 350 0 times, leaving a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 42102.831
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 13:
When dividing 3500 by 515, we get 6 with a remainder of 410.
The next digit of our result is 6. 
Result so far: 42102.83106
The remainder is 410 after subtracting 3090 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 14:
The number 515 fits into 4100 7 times, leaving a remainder of 495.
Use 7 as the next digit of our solution. 
Result so far: 42102.831067
The remainder is 495 after subtracting 3605 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 15:
When dividing 4950 by 515, we get 9 with a remainder of 315.
Use 9 as the next digit of our solution. 
Result so far: 42102.8310679
Deduct 4635 from 4950 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 16:
515 can be fit into 3150 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 42102.83106796
If we subtract 3090 from 3150, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 42102.83106796 with a remainder of 6e-08.
