We look at the division of 7249233 by 582 
The aim is to understand the frequency of 582 in 7249233.

Advancing to step 1:
The number 582 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 582

Going ahead to step 2:
582 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 582

On to step 3:
The number 582 fits into 724 1 times, leaving a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 582 from 724, we get 142.
Fetch the next digit (9) from the dividend, attach it to 142 and continue: 1429 / 582

Step 4:
582 goes into 1429 2 times with a remainder of 265.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1164 from 1429 and we're left with 265.
Fetch the next digit (2) from the dividend, attach it to 265 and continue: 2652 / 582

Let's proceed to step 5:
The number 582 fits into 2652 4 times, leaving a remainder of 324.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
The remainder is 324 after subtracting 2328 from 2652.
Bring next digit (3) of the dividend behind the 324 and repeat the process: 3243 / 582

Moving on to step 6:
The number 582 fits into 3243 5 times, leaving a remainder of 333.
Write down 5 as next digit of the result. 
Result so far: 1245.0
Deduct 2910 from 3243 and we're left with 333.
Append the next digit (3) from the dividend to 333 and continue with: 3333 / 582

On to step 7:
When dividing 3333 by 582, we get 5 with a remainder of 423.
Record the quotient 5 as the next digit in the result. 
Result so far: 12455.0
Subtracting 2910 from 3333 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 8:
When dividing 4230 by 582, we get 7 with a remainder of 156.
The number 7 becomes the next digit in our result. 
Result so far: 12455.7
The remainder is 156 after subtracting 4074 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 9:
The number 582 fits into 1560 2 times, leaving a remainder of 396.
Put 2 as the next digit of the answer. 
Result so far: 12455.72
If we take 1164 away from 1560, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 10:
582 goes into 3960 6 times with a remainder of 468.
Write down 6 as next digit of the result. 
Result so far: 12455.726
If we take 3492 away from 3960, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 11:
582 can be fit into 4680 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 12455.7268
Subtract 4656 from 4680 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
582 can be fit into 240 0 times, resulting in a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 12455.7268
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
582 can be fit into 2400 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 12455.726804
If we subtract 2328 from 2400, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
582 goes into 720 1 times with a remainder of 138.
Put 1 as the next digit of the answer. 
Result so far: 12455.7268041
If we subtract 582 from 720, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 15:
If we divide 1380 by 582, we get 2 and a remainder of 216.
The next digit of our result is 2. 
Result so far: 12455.72680412
If we subtract 1164 from 1380, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Our division results in 12455.72680412 with a remaining 2.16e-07.
