78726045 ÷ 582 
The aim is to understand the frequency of 582 in 78726045.

On to step 1:
When dividing 7 by 582, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 582

Advancing to step 2:
582 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 582

Step 3:
582 goes into 787 1 times with a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 582 from 787, we get 205.
Include the next digit (2) from the dividend after 205, then repeat: 2052 / 582

On to step 4:
The number 582 fits into 2052 3 times, leaving a remainder of 306.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 306 after subtracting 1746 from 2052.
Append the next digit (6) from the dividend to 306 and continue with: 3066 / 582

Step 5:
If we divide 3066 by 582, we get 5 and a remainder of 156.
The next digit of our result is 5. 
Result so far: 135.0
If we subtract 2910 from 3066, we get 156.
Append the next digit (0) from the dividend to 156 and continue with: 1560 / 582

Let's proceed to step 6:
1560 divided by 582 is 2 with a remainder of 396.
The next digit of our result is 2. 
Result so far: 1352.0
Deduct 1164 from 1560 and we're left with 396.
Take the next digit (4) from the dividend and append it to 396, then repeat: 3964 / 582

Going ahead to step 7:
3964 divided by 582 is 6 with a remainder of 472.
Put 6 as the next digit of the answer. 
Result so far: 13526.0
Subtract 3492 from 3964 to get 472.
Take the next digit (5) from the dividend and append it to 472, then repeat: 4725 / 582

Going ahead to step 8:
If we divide 4725 by 582, we get 8 and a remainder of 69.
The next digit of our result is 8. 
Result so far: 135268.0
If we subtract 4656 from 4725, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
The number 582 fits into 690 1 times, leaving a remainder of 108.
Record the quotient 1 as the next digit in the result. 
Result so far: 135268.1
Deduct 582 from 690 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
If we divide 1080 by 582, we get 1 and a remainder of 498.
Use 1 as the next digit of our solution. 
Result so far: 135268.11
Deduct 582 from 1080 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

After the division, we end up with 135268.11 and a remainder of 0.498.
