We're dividing 99579144 by 618 
The aim is to understand the frequency of 618 in 99579144.

Moving on to step 1:
If we divide 9 by 618, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 618

Advancing to step 2:
When dividing 99 by 618, we get 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 618

Step 3:
When dividing 995 by 618, we get 1 with a remainder of 377.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 618 away from 995, we end up with 377.
Grab the next digit (7) from the dividend, add it to 377, then carry on: 3777 / 618

Let's proceed to step 4:
If we divide 3777 by 618, we get 6 and a remainder of 69.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3708 from 3777, we get 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 618

Moving on to step 5:
618 can be fit into 699 1 times, resulting in a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 161.0
Subtracting 618 from 699 leaves us with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 618

Going ahead to step 6:
618 can be fit into 811 1 times, resulting in a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 1611.0
Subtracting 618 from 811 leaves us with 193.
Fetch the next digit (4) from the dividend, attach it to 193 and continue: 1934 / 618

Step 7:
When dividing 1934 by 618, we get 3 with a remainder of 80.
The number 3 becomes the next digit in our result. 
Result so far: 16113.0
If we subtract 1854 from 1934, we get 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 618

On to step 8:
618 can be fit into 804 1 times, resulting in a remainder of 186.
Use 1 as the next digit of our solution. 
Result so far: 161131.0
Subtracting 618 from 804 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 9:
When dividing 1860 by 618, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 161131.3
If we subtract 1854 from 1860, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
60 divided by 618 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 161131.3
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
600 divided by 618 is 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 161131.3
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 161131.3 with a balance of 0.06.
