Let's divide 82400298 by 685
The aim is to understand the frequency of 685 in 82400298.

Advancing to step 1:
8 divided by 685 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 685

Going ahead to step 2:
82 divided by 685 is 0 with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Bring next digit (4) of the dividend behind the 82 and repeat the process: 824 / 685

On to step 3:
685 can be fit into 824 1 times, resulting in a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 685 away from 824, we end up with 139.
Grab the next digit (0) from the dividend, add it to 139, then carry on: 1390 / 685

Let's proceed to step 4:
1390 divided by 685 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1370 from 1390, we get 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 685

Moving on to step 5:
The number 685 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we take 0 away from 200, we end up with 200.
Include the next digit (2) from the dividend after 200, then repeat: 2002 / 685

Moving on to step 6:
685 can be fit into 2002 2 times, resulting in a remainder of 632.
Use 2 as the next digit of our solution. 
Result so far: 1202.0
If we take 1370 away from 2002, we end up with 632.
Include the next digit (9) from the dividend after 632, then repeat: 6329 / 685

Going ahead to step 7:
6329 divided by 685 is 9 with a remainder of 164.
The next digit of our result is 9. 
Result so far: 12029.0
Subtract 6165 from 6329 to get 164.
Bring next digit (8) of the dividend behind the 164 and repeat the process: 1648 / 685

Moving on to step 8:
685 goes into 1648 2 times with a remainder of 278.
The number 2 becomes the next digit in our result. 
Result so far: 120292.0
Deduct 1370 from 1648 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 9:
685 goes into 2780 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 120292.4
Subtracting 2740 from 2780 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 685, we get 0 and a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 120292.4
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
If we divide 4000 by 685, we get 5 and a remainder of 575.
The next digit of our result is 5. 
Result so far: 120292.405
The remainder is 575 after subtracting 3425 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 12:
When dividing 5750 by 685, we get 8 with a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 120292.4058
The remainder is 270 after subtracting 5480 from 5750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 13:
2700 divided by 685 is 3 with a remainder of 645.
Put 3 as the next digit of the answer. 
Result so far: 120292.40583
Subtract 2055 from 2700 to get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Let's proceed to step 14:
When dividing 6450 by 685, we get 9 with a remainder of 285.
The number 9 becomes the next digit in our result. 
Result so far: 120292.405839
If we take 6165 away from 6450, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 15:
685 goes into 2850 4 times with a remainder of 110.
The number 4 becomes the next digit in our result. 
Result so far: 120292.4058394
The remainder is 110 after subtracting 2740 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 16:
685 goes into 1100 1 times with a remainder of 415.
The number 1 becomes the next digit in our result. 
Result so far: 120292.40583941
The remainder is 415 after subtracting 685 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

After the division, we end up with 120292.40583941 and a remainder of 4.15e-07.
