We look at the division of 21530303 by 682 
The aim is to understand the frequency of 682 in 21530303.

Step 1:
When dividing 2 by 682, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 682

Let's proceed to step 2:
21 divided by 682 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 682

Moving on to step 3:
When dividing 215 by 682, we get 0 with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Fetch the next digit (3) from the dividend, attach it to 215 and continue: 2153 / 682

Advancing to step 4:
The number 682 fits into 2153 3 times, leaving a remainder of 107.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2046 from 2153 leaves us with 107.
Append the next digit (0) from the dividend to 107 and continue with: 1070 / 682

On to step 5:
682 goes into 1070 1 times with a remainder of 388.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 682 away from 1070, we end up with 388.
Grab the next digit (3) from the dividend, add it to 388, then carry on: 3883 / 682

Let's proceed to step 6:
682 can be fit into 3883 5 times, resulting in a remainder of 473.
The next digit of our result is 5. 
Result so far: 315.0
Subtract 3410 from 3883 to get 473.
Include the next digit (0) from the dividend after 473, then repeat: 4730 / 682

On to step 7:
682 can be fit into 4730 6 times, resulting in a remainder of 638.
Record the quotient 6 as the next digit in the result. 
Result so far: 3156.0
Deduct 4092 from 4730 and we're left with 638.
Append the next digit (3) from the dividend to 638 and continue with: 6383 / 682

On to step 8:
When dividing 6383 by 682, we get 9 with a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 31569.0
If we take 6138 away from 6383, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 9:
682 can be fit into 2450 3 times, resulting in a remainder of 404.
Use 3 as the next digit of our solution. 
Result so far: 31569.3
If we subtract 2046 from 2450, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 10:
When dividing 4040 by 682, we get 5 with a remainder of 630.
Put 5 as the next digit of the answer. 
Result so far: 31569.35
The remainder is 630 after subtracting 3410 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 11:
682 can be fit into 6300 9 times, resulting in a remainder of 162.
Put 9 as the next digit of the answer. 
Result so far: 31569.359
If we take 6138 away from 6300, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 12:
If we divide 1620 by 682, we get 2 and a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 31569.3592
Subtracting 1364 from 1620 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 13:
2560 divided by 682 is 3 with a remainder of 514.
Write down 3 as next digit of the result. 
Result so far: 31569.35923
If we subtract 2046 from 2560, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Step 14:
682 can be fit into 5140 7 times, resulting in a remainder of 366.
The next digit of our result is 7. 
Result so far: 31569.359237
Deduct 4774 from 5140 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 15:
When dividing 3660 by 682, we get 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 31569.3592375
If we take 3410 away from 3660, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 16:
When dividing 2500 by 682, we get 3 with a remainder of 454.
The number 3 becomes the next digit in our result. 
Result so far: 31569.35923753
Subtract 2046 from 2500 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

The final result is 31569.35923753 with a remainder of 4.54e-07.
