We're dividing 87550757 by 579 
The aim is to understand the frequency of 579 in 87550757.

Moving on to step 1:
The number 579 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 579

Going ahead to step 2:
If we divide 87 by 579, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (5) from the dividend to 87 and continue with: 875 / 579

Step 3:
579 can be fit into 875 1 times, resulting in a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 296 after subtracting 579 from 875.
Take the next digit (5) from the dividend and append it to 296, then repeat: 2965 / 579

Going ahead to step 4:
579 goes into 2965 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2895 from 2965 leaves us with 70.
Append the next digit (0) from the dividend to 70 and continue with: 700 / 579

On to step 5:
700 divided by 579 is 1 with a remainder of 121.
The next digit of our result is 1. 
Result so far: 151.0
The remainder is 121 after subtracting 579 from 700.
Fetch the next digit (7) from the dividend, attach it to 121 and continue: 1217 / 579

Step 6:
The number 579 fits into 1217 2 times, leaving a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 1512.0
Deduct 1158 from 1217 and we're left with 59.
Append the next digit (5) from the dividend to 59 and continue with: 595 / 579

Going ahead to step 7:
When dividing 595 by 579, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 15121.0
If we subtract 579 from 595, we get 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 579

On to step 8:
167 divided by 579 is 0 with a remainder of 167.
The next digit of our result is 0. 
Result so far: 151210.0
Deduct 0 from 167 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 9:
When dividing 1670 by 579, we get 2 with a remainder of 512.
Use 2 as the next digit of our solution. 
Result so far: 151210.2
If we take 1158 away from 1670, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 10:
579 goes into 5120 8 times with a remainder of 488.
The next digit of our result is 8. 
Result so far: 151210.28
If we subtract 4632 from 5120, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 11:
579 goes into 4880 8 times with a remainder of 248.
The number 8 becomes the next digit in our result. 
Result so far: 151210.288
The remainder is 248 after subtracting 4632 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final result is 151210.288 with a remainder of 0.0248.
