We look at the division of 37840548 by 579 
The aim is to understand the frequency of 579 in 37840548.

On to step 1:
579 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 579

Moving on to step 2:
579 can be fit into 37 0 times, resulting in a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 579

Advancing to step 3:
579 goes into 378 0 times with a remainder of 378.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 378 to get 378.
Include the next digit (4) from the dividend after 378, then repeat: 3784 / 579

Let's proceed to step 4:
The number 579 fits into 3784 6 times, leaving a remainder of 310.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 3474 from 3784 leaves us with 310.
Bring next digit (0) of the dividend behind the 310 and repeat the process: 3100 / 579

Step 5:
When dividing 3100 by 579, we get 5 with a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we take 2895 away from 3100, we end up with 205.
Grab the next digit (5) from the dividend, add it to 205, then carry on: 2055 / 579

Let's proceed to step 6:
When dividing 2055 by 579, we get 3 with a remainder of 318.
The next digit of our result is 3. 
Result so far: 653.0
Subtract 1737 from 2055 to get 318.
Append the next digit (4) from the dividend to 318 and continue with: 3184 / 579

On to step 7:
579 can be fit into 3184 5 times, resulting in a remainder of 289.
Use 5 as the next digit of our solution. 
Result so far: 6535.0
Subtracting 2895 from 3184 leaves us with 289.
Fetch the next digit (8) from the dividend, attach it to 289 and continue: 2898 / 579

Going ahead to step 8:
When dividing 2898 by 579, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 65355.0
The remainder is 3 after subtracting 2895 from 2898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 579, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 65355.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 579 is 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 65355.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 65355.0 with a remainder of 0.3.
