We look at the division of 8320536 by 490 
The aim is to understand the frequency of 490 in 8320536.

Let's proceed to step 1:
If we divide 8 by 490, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 490

Moving on to step 2:
490 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 490

Step 3:
The number 490 fits into 832 1 times, leaving a remainder of 342.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 490 away from 832, we end up with 342.
Fetch the next digit (0) from the dividend, attach it to 342 and continue: 3420 / 490

Moving on to step 4:
3420 divided by 490 is 6 with a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2940 from 3420 leaves us with 480.
Grab the next digit (5) from the dividend, add it to 480, then carry on: 4805 / 490

Advancing to step 5:
4805 divided by 490 is 9 with a remainder of 395.
Write down 9 as next digit of the result. 
Result so far: 169.0
Deduct 4410 from 4805 and we're left with 395.
Include the next digit (3) from the dividend after 395, then repeat: 3953 / 490

Advancing to step 6:
The number 490 fits into 3953 8 times, leaving a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 1698.0
Subtract 3920 from 3953 to get 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 490

Advancing to step 7:
490 can be fit into 336 0 times, resulting in a remainder of 336.
Put 0 as the next digit of the answer. 
Result so far: 16980.0
Subtracting 0 from 336 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 8:
490 goes into 3360 6 times with a remainder of 420.
Put 6 as the next digit of the answer. 
Result so far: 16980.6
The remainder is 420 after subtracting 2940 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 9:
The number 490 fits into 4200 8 times, leaving a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 16980.68
If we subtract 3920 from 4200, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
490 can be fit into 2800 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 16980.685
Subtracting 2450 from 2800 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.

Going ahead to step 11:
3500 divided by 490 is 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 16980.6857
Subtract 3430 from 3500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
If we divide 700 by 490, we get 1 and a remainder of 210.
The number 1 becomes the next digit in our result. 
Result so far: 16980.68571
If we subtract 490 from 700, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
490 can be fit into 2100 4 times, resulting in a remainder of 140.
The next digit of our result is 4. 
Result so far: 16980.685714
If we take 1960 away from 2100, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
1400 divided by 490 is 2 with a remainder of 420.
The next digit of our result is 2. 
Result so far: 16980.6857142
If we subtract 980 from 1400, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 15:
490 goes into 4200 8 times with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 16980.68571428
Subtracting 3920 from 4200 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 16980.68571428 and a remainder of 2.8e-07.
